Problem with Roundcube (sending) SMTP error: Authentication failure: STARTTLS failed

[MMarko]

A quick update. I was playing around with the roundcube configuration (usr/local/cpanel/base/3rdparty/roundcube/config/main.inc.php) and noticed a workaround until the module is patched/updated. This workaround normally shouldnt work, but seems to work with the current problem in the module.

normally there is a series of lines which should read like this:

// SMTP username (if required) if you use %u as the username RoundCube
// will use the current username for login
$rcmail_config['smtp_user'] = '%u';

for now Roundcube seems to work properly if you change it to this:

// SMTP username (if required) if you use %u as the username RoundCube
// will use the current username for login
$rcmail_config['smtp_user'] = '';

This helped, thanks I had that problem when roundcube is stuck at "sending..."

I had to do this also to get roundcube to work. Thank you Sirbrent-

I am very glad the workaround I discovered has been useful to so many people!

However, anybody else noticing that on the disk usage in roundcube it says unlimited?

Best,

This has not happened with me, mail quotas are still properly recognized in roundcube on my servers.

This problem has resurfaced in S38506!

AAARRRRGG!

cPanel 11.24.5-S38506 - WHM 11.24.2 - X 3.9

For now I patched the configuration file.

AAARRRRGG!

cPanel 11.24.5-S38506 - WHM 11.24.2 - X 3.9

For now I patched the configuration file.

For reference, the STABLE build mentioned (11.24.5-STABLE_38506) was updated August 25, 2009.

If the Roundcube error log indicated the same message as reported in the original post of this thread, the following command should correct the issue:

# /scripts/autorepair net_smtp_fix

Kindly check the email error logs for the exact error message. You can get the email logs from /var/log/exim_mainlog.

I used the same command and rolled back changes to the RC config file.

I hoped it might be automated by this point, but perhaps... =)

Kindly check the email error logs for the exact error message. You can get the email logs from /var/log/exim_mainlog.

In addition to checking the Exim log, will help to check the specific Roundcube logs that are located at the following paths:

/var/cpanel/roundcube/log/console
/var/cpanel/roundcube/log/errors
/var/cpanel/roundcube/log/sendmail

Via root SSH access, the following command may be used to monitor the Roundcube logs while sending a test message in attempt to trigger the issue (and to see the resulting error details that are logged):

# tail -fvn0 /var/cpanel/roundcube/log/*
