for issue #186 by morki, thanks for reporting and providing sample favicons.
generated by the mentioned generator at favicon.io, with the ubuntu font and a
fuchsia-like color.
the favicon is served for listeners/domains that have the
admin/account/webmail/webapi endpoints enabled, i.e. user-facing. the mta-sts,
autoconfig, etc urls don't serve the favicon.
admins can create webhandler routes to serve another favicon. these webhandler
routes are evaluted before the favicon route (a "service handler").
otherwise, in dark mode, the plain text iframe content would be black text on
the white background of the iframe as set by webmail. i can't find a way to set
the content text on the iframe that contains it.
per listener, you could enable the admin/account/webmail/webapi handlers. but
that would serve those services on their configured paths (/admin/, /,
/webmail/, /webapi/) on all domains mox would be webserving, including any
non-mail domains. so your www.example/admin/ would be serving the admin web
interface, with no way to disabled that.
with this change, the admin interface is only served on requests to (based on
Host header):
- ip addresses
- the listener host name (explicitly configured in the listener, with fallback
to global hostname)
- "localhost" (for ssh tunnel/forwarding scenario's)
the account/webmail/webapi interfaces are served on the same domains as the
admin interface, and additionally:
- the client settings domains, as optionally configured in each Domain in
domains.conf. typically "mail.<yourdomain>".
this means the internal services are no longer served on other domains
configured in the webserver, e.g. www.example.org/admin/ will not be handled
specially.
the order of evaluation of routes/services is also changed:
before this change, the internal handlers would always be evaluated first.
with this change, only the system handlers for
MTA-STS/autoconfig/ACME-validation will be evaluated first. then the webserver
handlers. and finally the internal services (admin/account/webmail/webapi).
this allows an admin to configure overrides for some of the domains (per
hostname-matching rules explained above) that would normally serve these
services.
webserver handlers can now be configured that pass the request to an internal
service: in addition to the existing static/redirect/forward config options,
there is now an "internal" config option, naming the service
(admin/account/webmail/webapi) for handling the request. this allows enabling
the internal services on custom domains.
for issue #160 by TragicLifeHu, thanks for reporting!
bstore was updated to v0.0.6 to add this logging.
this simplifies some of the db-handling code in mtastsdb,tlsrptdb,dmarcdb. we
now call the package-level Init() and Close() in all tests properly.
- keep them on the right side of the window (more important now that we can resize)
- merge the close & cancel buttons into a close button, with a popup asking what to do for changes not saved as draft.
this started with looking into the dark mode of PR #163 by mattfbacon. it's a
very good solution, especially for the amount of code. while looking into dark
mode, some common problems with inverting colors are:
- box-shadow start "glowing" which isn't great. likewise, semitransparent
layers would become brighter, not darker.
- while popups/overlays in light mode just stay the same white, in dark mode
they should become lighter than the regular content because box shadows don't
give enough contrast in dark mode.
while looking at adding explicit styles for dark mode, it turns out that's
easier when we work more with css rules/classes instead of inline styles (so we
can use the @media rule).
so we now also create css rules instead of working with inline styles a lot.
benefits:
- creating css rules is useful for items that repeat. they'll have a single css
class. changing a style on a css class is now reflected in all elements of that
kind (with that class)
- css class names are helpful when inspecting the DOM while developing: they
typically describe the function of the element.
most css classes are defined near where they are used, often while making the
element using the class (the css rule is created on first use).
this changes moves colors used for styling to a single place in webmail/lib.ts.
each property can get two values: one for regular/light mode, one for dark mode.
that should prevent forgetting one of them and makes it easy to configure both.
this change sets colors for the dark mode. i think the popups look better than
in PR #163, but in other ways it may be worse. this is a start, we can tweak
the styling.
if we can reduce the number of needed colors some more, we could make them
configurable in the webmail settings in the future. so this is also a step
towards making the ui looks configurable as discussed in issue #107.
the members must currently all be addresses of local accounts.
a message sent to an alias is accepted if at least one of the members accepts
it. if no members accepts it (e.g. due to bad reputation of sender), the
message is rejected.
if a message is submitted to both an alias addresses and to recipients that are
members of the alias in an smtp transaction, the message will be delivered to
such members only once. the same applies if the address in the message
from-header is the address of a member: that member won't receive the message
(they sent it). this prevents duplicate messages.
aliases have three configuration options:
- PostPublic: whether anyone can send through the alias, or only members.
members-only lists can be useful inside organizations for internal
communication. public lists can be useful for support addresses.
- ListMembers: whether members can see the addresses of other members. this can
be seen in the account web interface. in the future, we could export this in
other ways, so clients can expand the list.
- AllowMsgFrom: whether messages can be sent through the alias with the alias
address used in the message from-header. the webmail knows it can use that
address, and will use it as from-address when replying to a message sent to
that address.
ideas for the future:
- allow external addresses as members. still with some restrictions, such as
requiring a valid dkim-signature so delivery has a chance to succeed. will
also need configuration of an admin that can receive any bounces.
- allow specifying specific members who can sent through the list (instead of
all members).

thanks to damir & marin from sartura for discussing requirements/features.
per mailbox, or for all mailboxes, in maildir/mbox format, in tar/tgz/zip
archive or without archive format for single mbox, single or recursive. the
webaccount already had an option to export all mailboxes, it now looks similar
to the webmail version.
if the message has a list-id header, we assume this is a (mailing) list
message, and we require a dkim/spf-verified domain (we prefer the shortest that
is a suffix of the list-id value). the rule we would add will mark such
messages as from a mailing list, changing filtering rules on incoming messages
(not enforcing dmarc policies). messages will be matched on list-id header and
will only match if they have the same dkim/spf-verified domain.
if the message doesn't have a list-id header, we'll ask to match based on
"message from" address.
we don't ask the user in several cases:
- if the destination/source mailbox is a special-use mailbox (e.g.
trash,archive,sent,junk; inbox isn't included)
- if the rule already exist (no point in adding it again).
- if the user said "no, not for this list-id/from-address" in the past.
- if the user said "no, not for messages moved to this mailbox" in the past.
we'll add the rule if the message was moved out of the inbox.
if the message was moved to the inbox, we check if there is a matching rule
that we can remove.
we now remember the "no" answers (for list-id, msg-from-addr and mailbox) in
the account database.
to implement the msgfrom rules, this adds support to rulesets for matching on
message "from" address. before, we could match on smtp from address (and other
fields). rulesets now also have a field for comments. webmail adds a note that
it created the rule, with the date.
manual editing of the rulesets is still in the webaccount page. this webmail
functionality is just a convenient way to add/remove common rules.
in top-left direction. keep textarea filling the height.
remember size in localstorage, only apply either width and/or height when
viewport width/height was the same as when the remembered width/height was set
(independently).
no visual indicator other than a cursor indicating resizability.
the regular send shortcut is control+Enter. the shift enables "archive thread".
there is no configuration option, you'll always get the button, but only for
reply/forward, not for new compose.
we may do "send and move thread to thrash", but let's wait until people want it.
for github issue #135 by mattfbacon
when sending a message with bcc's, prepend the bcc header to the message we
store in the sent folder. still not in the message we send to the recipients.
for applications to compose/send messages, receive delivery feedback, and
maintain suppression lists.
this is an alternative to applications using a library to compose messages,
submitting those messages using smtp, and monitoring a mailbox with imap for
DSNs, which can be processed into the equivalent of suppression lists. but you
need to know about all these standards/protocols and find libraries. by using
the webapi & webhooks, you just need a http & json library.
unfortunately, there is no standard for these kinds of api, so mox has made up
yet another one...
matching incoming DSNs about deliveries to original outgoing messages requires
keeping history of "retired" messages (delivered from the queue, either
successfully or failed). this can be enabled per account. history is also
useful for debugging deliveries. we now also keep history of each delivery
attempt, accessible while still in the queue, and kept when a message is
retired. the queue webadmin pages now also have pagination, to show potentially
large history.
a queue of webhook calls is now managed too. failures are retried similar to
message deliveries. webhooks can also be saved to the retired list after
completing. also configurable per account.
messages can be sent with a "unique smtp mail from" address. this can only be
used if the domain is configured with a localpart catchall separator such as
"+". when enabled, a queued message gets assigned a random "fromid", which is
added after the separator when sending. when DSNs are returned, they can be
related to previously sent messages based on this fromid. in the future, we can
implement matching on the "envid" used in the smtp dsn extension, or on the
"message-id" of the message. using a fromid can be triggered by authenticating
with a login email address that is configured as enabling fromid.
suppression lists are automatically managed per account. if a delivery attempt
results in certain smtp errors, the destination address is added to the
suppression list. future messages queued for that recipient will immediately
fail without a delivery attempt. suppression lists protect your mail server
reputation.
submitted messages can carry "extra" data through the queue and webhooks for
outgoing deliveries. through webapi as a json object, through smtp submission
as message headers of the form "x-mox-extra-<key>: value".
to make it easy to test webapi/webhooks locally, the "localserve" mode actually
puts messages in the queue. when it's time to deliver, it still won't do a full
delivery attempt, but just delivers to the sender account. unless the recipient
address has a special form, simulating a failure to deliver.
admins now have more control over the queue. "hold rules" can be added to mark
newly queued messages as "on hold", pausing delivery. rules can be about
certain sender or recipient domains/addresses, or apply to all messages pausing
the entire queue. also useful for (local) testing.
new config options have been introduced. they are editable through the admin
and/or account web interfaces.
the webapi http endpoints are enabled for newly generated configs with the
quickstart, and in localserve. existing configurations must explicitly enable
the webapi in mox.conf.
gopherwatch.org was created to dogfood this code. it initially used just the
compose/smtpclient/imapclient mox packages to send messages and process
delivery feedback. it will get a config option to use the mox webapi/webhooks
instead. the gopherwatch code to use webapi/webhook is smaller and simpler, and
developing that shaped development of the mox webapi/webhooks.
for issue #31 by cuu508
The `TransportDirect` transport allows to tweak outgoing SMTP
connections to remote servers. Currently, it only allows to select
network IP family (ipv4, ipv6 or both).
For example, to disable ipv6 for all outgoing SMTP connections:
- add these lines in mox.conf to create a new transport named
"disableipv6":
```
Transports:
disableipv6:
Direct:
DisableIpv6: true
```
- then add these lines in domains.conf to use this transport:
```
Routes:
-
Transport: disableipv6
```
fix#149
- add option to put messages in the queue "on hold", preventing delivery
attempts until taken off hold again.
- add "hold rules", to automatically mark some/all submitted messages as "on
hold", e.g. from a specific account or to a specific domain.
- add operation to "fail" a message, causing a DSN to be delivered to the
sender. previously we could only drop a message from the queue.
- update admin page & add new cli tools for these operations, with new
filtering rules for selecting the messages to operate on. in the admin
interface, add filtering and checkboxes to select a set of messages to operate
on.
by explaining (in the titles/hovers) what the concepts and requirements are, by
using selects/dropdowns or datalist suggestions where we have a known list, by
automatically suggesting a good account name, and putting the input fields in a
more sensible order.
based on issue #132 by ally9335
before, an error about an invalid address was not used, causing a delivery
attempt to an empty address (empty localpart/domain). delivery to that address
would fail, but we should've prevented that message from being queued at all.
additionally, an error in adding the message to the queue was ignored too.
an é (e with accent) can also be written as e+\u0301. the first form is NFC,
the second NFD. when logging in, we transform usernames (email addresses) to
NFC. so both forms will be accepted. if a client is using NFD, they can log
in too.
for passwords, we apply the PRECIS "opaquestring", which (despite the name)
transforms the value too: unicode spaces are replaced with ascii spaces. the
string is also normalized to NFC. PRECIS may reject confusing passwords when
you set a password.
both when parsing our configs, and for incoming on smtp or in messages.
so we properly compare things like é and e+accent as equal, and accept the
different encodings of that same address.
transferring the data only once. we only do this when the recipient domains
are the same. when queuing, we now take care to set the same NextAttempt
timestamp, so queued messages are actually eligable for combined delivery.
this adds a DeliverMultiple to the smtp client. for pipelined requests, it will
send all RCPT TO (and MAIL and DATA) in one go, and handles the various
responses and error conditions, returning either an overal error, or per
recipient smtp responses. the results of the smtp LIMITS extension are also
available in the smtp client now.
this also takes the "LIMITS RCPTMAX" smtp extension into account: if the server
only accepts a single recipient, we won't send multiple.
if a server doesn't announce a RCPTMAX limit, but still has one (like mox does
for non-spf-verified transactions), we'll recognize code 452 and 552 (for
historic reasons) as temporary error, and try again in a separate transaction
immediately after. we don't yet implement "LIMITS MAILMAX", doesn't seem likely
in practice.
actually, this fix can reduce focus changes for more operations. withStatus is
often used to show an operation in progress in the status bar, only when the
operation isn't done within 1 second. we would restore focus to the element
before the operation started. that was done because we disable elements
sometimes (preventing duplicate form submission). for things like the
autocomplete, with the tab key, which also moves focus to the next element, we
don't want that focus switched back again.
the smtp extension, rfc 4865.
also implement in the webmail.
the queueing/delivery part hardly required changes: we just set the first
delivery time in the future instead of immediately.
still have to find the first client that implements it.
to start composing a message.
the help popup now has a button to register the "mailto:" links with the mox
webmail (typically only works over https, not all browsers support it).
the mailto links are specified in 6068. we support the to/cc/bcc/subject/body
parameters. other parameters should be seen as custom headers, but we don't
support messages with custom headers at all at the moment, so we ignore them.
we now also turn text of the form "mailto:user@host" into a clickable link
(will not be too common). we could be recognizing any "x@x.x" as email address
and make them clickable in the future.
thanks to Hans-Jörg for explaining this functionality.
before, we showed the xn-- ascii names, along with the unicode name. but users
of internationalized email don't want to see any xn-- names. we now put those
in an html title attribute for some cases, so you can still see them if you
really want to, by hovering.
after talking to arnt at fosdem.
