Plesk HORDE [error] [imp] FAILED LOGIN

We had a small issue with Horde webmail on one of our CentOS Plesk 8.6 server. The problem was we were not able to login into Horde Webmail and were getting login failed error. The logs under /var/log/psa-horde/psa-horde.log showed something like this.

HORDE [error] [imp] FAILED LOGIN xxx.xxx.xxx.xxx to localhost:143[imap/notls] as info@domain.co.uk [on line 258 of "/usr/share/psa-horde/imp/lib/Auth/imp.php"]

Solution.

Make sure you can telnet to port 143 from the server itself. For ex.

[root@server] telnet localhost 143

If you receive connection refused error please Check the /etc/hosts file and make sure that it has localhost entry as shown below.

127.0.0.1 localhost

If the problem is still not resolved and you still get thos errors then just re-install the IMAP Service on the server. Following are the steps used to re-install 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@server]# pwd
/root/plesk/dist-rpm-CentOS-4.2-i386/base

[root@server]# 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

I hope with the above methods you should be able to resolve the horde login failed error on your plesk server.
