Login Problems with IMAP, Courier on Webinterface (Horde / Roundcube) in Plesk 11.5

[poppsworld.com]

Hello,

since some days we are facing problems logging in, into our webinterface (we tried both: roundcube and horde) in Plesk Version 11.5.30 Update #12 on a CENTOS 6.X-Machine.

When trying to login to the E-Mail Webinterface we receive timeouts:

tail -f /var/log/plesk-roundcube/errors shows:

[22-Aug-2013 14:02:56 +0200]: IMAP Error: Login failed for XXX from X.X.X.X. Could not connect to localhost:143: Die Wartezeit für die Verbindung ist abgelaufen in /usr/share/psa-roundcube/program/include/rcube_imap.php on line 191 (POST /?_task=login&_action=login)

--> Timeout

tail -f /usr/local/psa/var/log/maillog shows:

Aug 22 14:08:54 XXX courier-imapd: LOGOUT, ip=[::ffff:127.0.0.1], rcvd=12, sent=365

Aug 22 14:08:54 XXX courier-imaps: LOGOUT, ip=[::ffff:127.0.0.1], rcvd=12, sent=356

But Courier-IMAP seems to run. I can login (after some time... it takes some seconds to connect):

telnet localhost 143
Trying ::1...
telnet: connect to address ::1: Connection timed out
Trying 127.0.0.1...
Connected to localhost.

Actually i have no idea how to fix this. Can anyone help me with this issue?


Thanks and best regards

Same for Horde:

Small update:

After changing line 57 in /usr/share/psa-roundcube/config/main.inc.php

from

$rcmail_config['default_host'] = 'localhost';

to

$rcmail_config['default_host'] = '127.0.0.1';

i can login using roundcube.

Changing line 301 in /usr/share/psa-horde/imp/config/backends.php to:

    'hostspec' => '127.0.0.1',

i can login using horde.

Seems like some name-resolving or maybe DNS-issue in Centos/Plesk?

My /etc/hosts looks like this:

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

Make sure that you have following line in /etc/hosts:

127.0.0.1 localhost.localdomain localhost

Make sure that you have following line in /etc/hosts:

127.0.0.1 localhost.localdomain localhost

Well but... i have a similar line in my /etc/hosts?
