suddenly 'User unknown'?

[Dan White]

Do you otherwise see log entries for an imap connection?

Is there a permissions problem on the lmtpunix mux
(/var/lib/imap/socket/lmtp)? Your syslog entry seems to indicate it is
communicating with cyrus, but perhaps I'm misreading it.

Look up telemetry logging, and lmtptest for other ways to verify your cyrus
config. You may need to temporarily enable lmtp on a TCP port to test.
