Hello,
we implemented a submission server with SASL authentication. nothing special... also we use to grep for "sasl_username=$customer_with_trouble". today I noticed, the successful authentication was not logged because a sender address was rejected. Looks like sasl_username logging happen only with a valid QueueID which is not available in some cases. I only assume the authentication was successful by the final log entry mention "auth=1" postfix/submission/smtpd[31338]: connect from foo.example.org[192.0.2.25] postfix/submission/smtpd[31338]: Anonymous TLS connection established from foo.example.org[192.0.2.25]: TLSv1 with cipher $not_important_here postfix/submission/smtpd[31338]: NOQUEUE: reject: RCPT from foo.example.org[192.0.2.25]: 550 5.1.0 <unknown_sen...@example.org>: Sender address rejected: User unknown; ... postfix/submission/smtpd[31338]: disconnect from foo.example.org[192.0.2.25] ehlo=2 starttls=1 auth=1 mail=1 rcpt=0/1 quit=1 commands=6/7 would it make sense / be possible to log successful authentication always?
