Hi, I have inherited a cyrus / postfix server, which is generally well-behaved. However, there is an intermittent error when delivering messages to a certain mailbox. It is infrequent, and generally the message is delievered on the user's next attempt in his MUA. The log is something like: Mar 9 14:29:07 captain postfix/smtpd[20639]: connect from unknown[10.2.1.1] Mar 9 14:29:07 captain postfix/smtpd[20639]: D557618536: client=unknown[10.2.1.1] Mar 9 14:29:07 captain postfix/cleanup[20642]: D557618536: message-id=<49B52795.2010307@xxxxxxxxxxxxxxxxx> Mar 9 14:29:07 captain postfix/qmgr[15149]: D557618536: from=<mail@xxxxxxxxxxxxxxxxx>, size=67727, nrcpt=1 (queue active) Mar 9 14:29:07 captain cyrus/lmtpunix[20645]: accepted connection Mar 9 14:29:07 captain cyrus/lmtpunix[20645]: lmtp connection preauth'd as postman Mar 9 14:29:07 captain cyrus/lmtpunix[20645]: verify_user(user.sirius-john) failed: Mailbox does not exits Mar 9 14:29:07 captain postfix/smtpd[20639]: disconnect from unknown[10.2.1.1] Mar 9 14:29:07 captain postfix/lmtp[20644]: D557618536: to=<sirius-john@xxxxxxxxxxxxxxxxx>, relay=captain.munged-domain.com[/var/run/cyrus/socket/lmtp], delay=0.1, delays=0.02/0.01/0/0.08, dsn=5.1.1, status=bounced (host captain.munged-domain.com[/var/run/cyrus/socket/lmtp] said: 550-Mailbox unknown.
