PROBLEM:
While Login into Webmail it returns the error: “Login failed”
SOLUTION:
Make sure that it is possible to connect to localhost:143 from the command line using telnet. If you get the error as below:
# telnet localhost 143 localhost/143: Name or service not known
then check /etc/hosts file. It must have permissions -rw-r–r– and contain the record for localhost in the following format:
127.0.0.1 localhost localhost.localdomain
Above is from From Parallels Knowledgebase
If /var/log/psa-horde/psa-horde.log shows something like:
FAILED LOGIN xx.xx.xx.xx to localhost:143[imap/notls] as me@mydomain.co.uk FAILED LOGIN xx.xx.xx.xx to localhost:143[imap/notls] as me@mydomain.co.uk
I have searched regarding this but unable to find any fix so, I just re-installed the IMAP Service on the server. Following are the steps using which I have re-installed IMAP Server:
1) You can find the RPMS used by Plesk in /root/psa/PSA_version directory OR you can download the Tar (Not Autoinstaller) containing RPMS from Parallels website http://www.parallels.com/en/download/ (need registration it’s free)
2) go to the RPM directory which contains courier Imap RPM’s
#cd [path to the PSA RPM Directory]/dist-rpm-CentOS-4.2-i386/base/
3) Re-install courier-imap-3.0.8-cos4.build81070322.16.i586.rpm and psa-courier-imap-add-8.1.1-cos4.build81070322.16.i586.rpm which will automatically restart the services too
[root@vps base]# pwd /root/plesk/dist-rpm-CentOS-4.2-i386/base [root@vps base]# rpm -Uvh courier-imap-3.0.8-cos4.build81070322.16.i586.rpm psa-courier-imap-add-8.1.1-cos4.build81070322.16.i586.rpm –force Preparing… ########################################### [100%] Reloading configuration: [ OK ] 1:courier-imap ########################################### [ 50%] Stopping Courier-IMAP server: Stopping imap [ OK ] Stopping imap-ssl [ OK ] Stopping pop3 [ OK ] Stopping pop3-ssl [ OK ] Starting Courier-IMAP server: Starting imapd [ OK ] Starting imap-ssl [ OK ] Starting pop3 [ OK ] Starting pop3-ssl [ OK ] 2:psa-courier-imap-add ########################################### [100%] Stopping Courier-IMAP server: Stopping imap [ OK ] Stopping imap-ssl [ OK ] Stopping pop3 [ OK ] Stopping pop3-ssl [ OK ] Starting Courier-IMAP server: Starting imapd [ OK ] Starting imap-ssl [ OK ] Starting pop3 [ OK ] Starting pop3-ssl [ OK ] [root@vps base]# netstat -nap | grep :143 tcp 0 0 0.0.0.0:143 0.0.0.0:* LISTEN 1657/couriertcpd [root@vps base]# telnet localhost 143 Trying 127.0.0.1… Connected to localhost. Escape character is ‘^]’.
After this I was able to login into Webmail without any problem. I hope this will help other to fix the issue too

Had this problem pop-up yesterday after trying to restart courier-imap.. Since as of PLESK 10 you are not allowed to remove individual packages i could’nt reinstall the package as described above.
Fixed the problem by editing the imapd
Added [code]AUTH=CRAM-MD5 AUTH=CRAM-SHA1[/code] to IMAP_CAPABILITY
