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

[Radio_Head]

All we know that you support only SPAMASSASSIN . However we were talking about the possibility to use Horde with "SMTP" such as in the past . With latest cpanel updates it was not possible and Horde email were passing directly to exim . However fixed, no problem at all.

That claim is not borne out by testing on unmodified servers. With the default installation of Horde and Roundcube, both performed SMTP Authentication.

 

[jassi]

vi /usr/local/cpanel/base/3rdparty/roundcube/config/main.inc.php

and changed

$rcmail_config['smtp_user'] = '%u';
to
$rcmail_config['smtp_user'] = '';

FIXED....

I've recently had this issue, can you tell me which versions of RELEASE and STABLE from cPanel has or will have this issue solved ? I've recently updated our cPanel server, but not all of them have been fixed.

Also, I've found on the error_log some messages like this:

PHP Warning:  ob_start() [<a href='ref.outcontrol'>ref.outcontrol</a>]: output handler 'ob_gzhandler' cannot be used after 'URL-Rewriter' in /usr/local/cpanel/base/3rdparty/roundcube/index.php on line 45
PHP Fatal error:  Call to a member function connect() on a non-object in /usr/local/cpanel/base/3rdparty/roundcube/program/include/rcmail.php on line 469

I'm not sure if they're related.

vi /usr/local/cpanel/base/3rdparty/roundcube/config/main.inc.php

and changed

$rcmail_config['smtp_user'] = '%u';
to
$rcmail_config['smtp_user'] = '';

fixed....

This totally fixes roundcube smtp issue, and is compatible with the csf smtp owner restriction ! You rock jassi !

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!

Thanks sirbrent! worked a treat!

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.

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.

 

[Promethyl]

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/*
