Roundcube hangs while sending mail (connection to socket timed out)

[gegervision]

I'm having the same issue. The fix editing the roundcube config did not work for me.

Please check for possible logged error detail from RoundCube; the following post details how to do this (using root SSH access while attempting to send in RoundCube):

It might be a known issue with an available fix, such as what is detailed in the following post (with example log detail for comparison):

it may be a CSF issue. I did the following after looking up my error:

But then I got this error in RoundCude Log:

[27-Oct-2009 19:39:33] Invalid response code received from server (550):

Here is my log results (not the same as mentioned in one of the link you provided below):

Are other webmail clients allowing to send without error, such as via Horde and SquirrelMail?

Is there a hardware or software firewall in-use; in particular a software firewall running on the same system might be interfering. An example of software firewalls might include an iptables-wrapper, like APF, CSF/LFD, or similar third-party scripts or custom iptables configurations.

[gegervision]

Yes CSF is running as I stated above. Was working fine until a few days ago.

Can I still run

# /scripts/autorepair net_smtp_fix

safely without causing any further issues.

I apologize as I missed your earlier message indicating CSF was in-use.

The autorepair script for "net_smtp_fix" should still be safe to run without causing further difficulty; to help reduce the number of variables I would try just one possible fix at a time where the issue is re-verified after attempting each corrective measure.

For CSF, please check the following configuration options:
SMTP_BLOCK
SMTP_ALLOWLOCAL
SMTP_PORTS

Specific to CSF, the following command (via root SSH access) may be used to view the current setting of the above options:

# grep -i "^SMTP_" /etc/csf/csf.conf

If using "SMTP_BLOCK" please ensure that "SMTP_ALLOWLOCAL" is enabled.

If that alone does not fix it, please try temporarily disabling CSF to further test RoundCube.

Same issue with all web mail scripts. I only had RoundCube enabled so I had to add the other in tweak setting to test.

My CSF/LFD has the following:

SMTP_BLOCK = 1 Default: 0
# If SMTP_BLOCK is enabled but you want to allow local connections to port 25
# on the server (e.g. for webmail or web scripts) then enable this option to
# allow outgoing SMTP connections to 127.0.0.1
SMTP_ALLOWLOCAL = 1 Default: 0

But i still get the errors

I got it working. Let me follow back what I did and will post what I did to resolve it. Thx for you help and quick responses.
