Can't log into any mail

[105547111]

I updated my FC4 server to SQL 5.0.24a and PHP 5.1.6

All is working fine. I did a sql privlidge update and that fixed any myphpadmin error messages.

Anyway all the sites are running but I cant log into any mail account on any domain.

All I get is 'wrong password' error.

Same on POP and webmail via horde.

I reset the password in plesk and its still the same.

Mail is running, by uysing spam assassin training messages are in the mail boxes.

Its just the blasted passwords..

Any idea's?
