Hi Joe,
I get hundreds of these lines in my logfile /var/log/messages.
Aug 26 23:19:54 server dovecot(pam_unix)[[8763]]: check pass; user unknown Aug 26 23:19:54 server dovecot(pam_unix)[[8763]]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost= Aug 26 23:27:09 server dovecot(pam_unix)[[8796]]: check pass; user unknown Aug 26 23:27:10 server dovecot(pam_unix)[[8796]]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost= Aug 26 23:34:22 server dovecot(pam_unix)[[8881]]: check pass; user unknown Aug 26 23:34:22 server dovecot(pam_unix)[[8881]]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost=
The past 11 hours I got 174 of these lines.
Any idea?
Regards, Leif
Hey Leif,
No idea. Does mail pickup actually work OK?
You might have a user that has configured querying of the server, but never got the username and password setup. I dunno why it would keep querying with no user data after being denied once, but maybe there's something buggy out there doing so.

Hi Joe,

I'll check your suggestion about "You might have a user that has configured querying....".
