Hi,

I am getting the following in
/usr/local/psa/var/log/maillog

Nov 6 02:38:26 core imapd: /usr/lib/courier-imap/libexec/authlib/authpsa: No such file or directory

Nov 6 02:40:15 core pop3d: /usr/lib/courier-imap/libexec/authlib/authpsa: No such file or directory

I can login to the control panel for any email OK, however, POP or WebMail gives this error.

System is Plesk 7.5.4 on CENT OS 3.5

Came after upgrade to 7.5.4 from an earlier 7.5.x version.


Thanks,
 
Don't forget to use the --force option.

cd /path/to/rpm/file
rpm -Uvh --force courier-imap

You would do well to check your upgrade installer log (usually in /tmp) check every line to see what else may have failed during the upgrade process.

Depending on what else may not have gone properly during the upgrade, you may have to re-install other rpm's as well.
