Mechiel Lukkien afb182cb14 smtpserver: add prometheus metric for failing starttls handshakes for incoming deliveries ... and add an alerting rule if the failure rate becomes >10% (e.g. expired certificate). the prometheus metrics includes a reason, including potential tls alerts, if remote smtp clients would send those (openssl s_client -starttls does). inspired by issue #237, where incoming connections were aborted by remote. such errors would show up as "eof" in the metrics.		2024-11-29 12:43:21 +01:00
