Can't login to webmail (no one receives mails anymore)

[hilario]

This morning none of my customers are receiving mails.

We can access the ourserver.com/webmail page and successfully login, but when you click in roundcube or horde you are redirected to a login failure page.

My server uses mailscanner. It is possible to see in mailwatch that mails are being sent, and also that mails are being received, but we can't pop the mails with any mail client (thunderbird or eudora in our case).

How can I trace this (where are the pop3 or whatever login files)?

I noticed that WHM has been updated during the night. Is it an issue with WHM 11.36.0 (build 2) ?

Should I revert to an older version? How do I do it?




Edit:
# netstat -nlap | grep exim
tcp 0 0 127.0.0.1:125 0.0.0.0:* LISTEN 25264/exim
tcp 0 0 127.0.0.1:125 127.0.0.1:52313 ESTABLISHED 25768/exim

# netstat -nlap | grep :25
tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 29826/perl
tcp 0 0 67.19.188.154:25 173.192.24.27:55451 TIME_WAIT -

# netstat -nlap | grep :110
#

This is showing assp is running on the default Exim port of 25 while pop is not running at all.

I can verify the issue with Roundcube not allowing login even with the test account I created. The exact error being presented is Connection to storage server failed

It's not possible to downgrade once you've updated to 11.36. You should contact ASSP about your mail issues, it's not a cPanel supported product.

It appears that the new update of cPanel has changed its dependencies to rpms from perl.
Is there a way to revert to the cPanel that was running yesterday?

 

[Infopro]

No. There is no way back from here.

There is word on the EDGE mailing list that an autofixer is being rolled up that might be of use to you here. I'll post back here the moment I hear more about that. If that's not acceptable to you, please do open a ticket to cPanel Technical Support at your earliest inconvenience.

I too think I am having the same issue. My server just autoupdated, and now we can't login to our mail server. We are using Exim. The service is running fine, but when we try to connect our email clients to download (via IMAP), no mail is received.

Any fixes?

We are not aware of a cPanel update causing this problem. Please submit a ticket so we can look at your server and assist you directly.
