the imapserver started with imap4rev2-only and utf8=only. to prevent potential issues with imaputf7, which makes "&" special, we refused any mailbox with an "&" in the name. we already tried decoding utf7, falling back to using a mailbox name verbatim. that behaviour wasn't great. we now treat the enabled extensions IMAP4rev2 and/or UTF8=ACCEPT as indication whether mailbox names are in imaputf7. if they are, the encoding must be correct. we now also send mailbox names in imaputf7 when imap4rev2/utf8=accept isn't enabled. and we now allow "*" and "%" (wildcard characters for matching) in mailbox names. not ideal for IMAP LIST with patterns, but not enough reason to refuse them in mailbox names. people that migrate may run into this, possibly as blocker. we also allow "#" in mailbox names, but not as first character, to prevent potential clashes with IMAP namespaces in the future. based on report from Damian Poddebniak using https://github.com/duesee/imap-flow and issue #110, thanks for reporting!
