qmail authentication problem with plesk

[janyona]

I run a virtual server that is using plesk. Recently qmail refuses to accept passwords for mailboxes for all domains in the server. user passwords dont work, a login screen simply keeps reappearing.
Please help with ideas why this is happening

Hello,

What can the users not login into?

Their admin page at port 8443, smtp sending email, pop3 downloading email, something else?

What version of Plesk are you running?

users cannot login to pop3 downloading email

Can you telnet to port 110 of your server? Do you get an error?

Do you have any errors in /usr/local/psa/var/log/maillog ?

Plesk defaults to a max of 40 connections and uses xinetd for managing the connections.

If you don't see any errors maybe something just got futzed up with Plesk.

You can restart pop with " /etc/init.d/courier-imap restart " (Yes, that has the pop in it too)
