All, I'm not sure if this is a cyrus error or a postfix error but, I can't find any information about how to resolve it. I'm seeing the following in /var/log/maillog: Jul 1 21:52:15 mail-server cyrus-imapd/master[11907]: process type:SERVICE name:lmtpunix path:/usr/lib/cyrus-imapd/lmtpd age:0.206s pid:12140 exited, status 75 Jul 1 21:52:15 mail-server postfix/lmtp[12036]: EB0C1E5B11: to=<user@xxxxxxxxxxx>, relay=mail-server[/var/lib/imap/socket/lmtp], delay=32177, delays=32169/6/2.6/0.02, dsn=4.3.0, status=deferred (host mail-server[/var/lib/imap/socket/lmtp] said: 421 4.3.0 lmtpd: Internal error: assertion failed: lib/cyrusdb_twoskip.c: 600: record->level <= MAXLEVEL (in reply to end of DATA command)) The really strange thing is some mail goes through and some does not. I haven't found any pattern to it yet. Any suggestions would be greatly appreciated.
