I have installer Qmail with POP3 on my server, running RedHat8. This works fine. Wanting to use a Webmail interface on my mails, i installed Courier IMAP server. When i tried to log on via Outlook Express, i'm denied access. I only made four changes in the /usr/lib/courier-imap/etc/imapd:
ADDRESS=my local ip address
If i use AUTHMODULES authpam, authpwd or authshadow, i get this message:
"Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems or a long period of inactivity."
If i use AUTHMODULES authdaemon, i get this message:
"The server has rejected your login. Please verify that your username and password are correct"
What can be the problem here?
