"Connection to IMAP server failed"

[psarema.gr]

Hello,

Since today I (and my clients) get this message when I try to connect to my webmail account

"Connection to IMAP server failed" with both Horde and Roundcube

I restarted cpanel but same problem again.
I tried to follow some sollutions (not exactly for the same problem but similar) with no luck, like the one posted in

WebMail problems...

Can you please advise me what to do?

[Scott Greczkows]

I have also been having this problem since yesterday.

I am running the latest current version.

Imap logs should be located in /var/log/maillog/

I'm having the same issue with not being able to connect to Imap server. All webmail (Horde, SqirrelMail, and RoundCube) seems to be broken.

Horde shows "Login failed because your username or password was entered incorrectly.",

SquirrelMail shows "Warning: fsockopen() [function.fsockopen]: unable to connect to localhost:143 (Connection refused) in /usr/local/cpanel/base/3rdparty/squirrelmail/plugins/login_auth/functions.php on line 129"

RoundCube shows "Connection to Imap server failed".

When webmail was working a few days ago, Imap logs were showing in /var/log/maillog/, but now Imap does not seem to be logging anymore.

I was able to fix webmail initially by updating CPanel - /scripts/upcp –force
But it seemed to break again shortly after that. I've noticed a lot of discussion here about this problem, but no solution, so I don't expect a reply. Just wanted to share my experience with webmail. Thanks.

Hello,

I ran into this problem a few days ago.

You can easily fix it by going to WHM > Service Configuration > IMAP Configuration. And enabling IMAP.

It is because IMAP has been upgraded within the whm update.

Hmm... that setting doesn't exist on my system. Maybe there's something else I need to enable. This is a fresh install of CPanel on a VPS running CentOS 5.2. WHM shows version information (top right) as:
cPanel 11.24.0-C30898 - WHM 11.24.0 - X 3.9
CENTOS 5.2 i686 on virtuozzo

I do see the setting you're referring to on one of our old servers (not VPS) at
Main >> Service Configuration >> IMAP Configuration.

I've tried enabling either mail server with name results.
Main >> Service Configuration >> Mailserver Selection (Courier and Dovecot).

For some reason, webmail started working again today. Hmm... maybe WHM/CPanel did an auto-update overnight. I'll have to check to logs. Well, everything is working perfectly on my new WHM/CPanel installation, so I'm a happy camper

Hmm... the webmail problem started all over again. No updates have been made.

Horde shows "Login failed because your username or password was entered incorrectly.",

SquirrelMail shows "Warning: fsockopen() [function.fsockopen]: unable to connect to localhost:143 (Connection refused) in /usr/local/cpanel/base/3rdparty/squirrelmail/plugins/login_auth/functions.php on line 129"

RoundCube shows "Connection to Imap server failed".

I have noticed that occasionally CPanel and WHM will say in the header "VPS Optimized 2", and sometimes just "VPS Optimized", indicating different versions.

If you are seeing from squirrel:

getaddrinfo failed: Name or service not known

check in /etc/hosts to see if there is a line:

127.0.0.1 localhost

if its not there, add it and webmail will magically work again

[sirotex]

Hello,

That is nothing to do with it... The problem is IMAP isnt Enabled, you will have to go and fish around in WHM for IMAP configuration editor

Which in the 11.24 cPanel version is now named 'Mailserver Configuration'

[duranduran]

Same problem here (and i have the 127.0.0.1 localhost in my /etc/hosts as well).

ERROR: Connection dropped by IMAP server.

Any fix ?

[rmackay]

Did this ever get fixed for you? I am seeing this problem now as well.

This issue seems to be randomly spreading across servers.

This issue only affects Horde and Roundcube? What about Squirrelmail? Are you able to telnet to port 143? What about use IMAP using an IMAP client on your workstation?

[Snowman30]

we have the same problem that everyone else is reporting

telnet to 143 says connection refused

ive tried almost everythign i can think of to correct this
