RoundCube Not Sending Emails (Cpanel)

Run this command in a shell prompt: tail -20 /var/cpanel/roundcube/log/errors

It might list errors like the following:
[30-May-2009 12:06:24] Invalid response code received from server (-1):
[30-May-2009 12:06:24] Invalid response code received from server (-1):
[30-May-2009 12:06:24] Invalid response code received from server (-1):
[30-May-2009 12:06:24 +0100] SMTP Error: SMTP error: Authentication failure: Invalid response code received from server (Code: -1)

If you’re getting errors whenever someone sends an email using Roundcube Webmail try the following:
/scripts/makecpphp

This will rebuild Cpanel/WHM php setup. This seems to work for some people so it’s worth a shot.

    Thank for this. I will give it a try. I have a new VPS with cPanel installed and have this problem with RoundCube.

    I tried the error command and I did have something similar to your errors. I will let you know how it goes.

    Nope, still not working even after sucessfully rebuilding cPanel’s PHP. Any other suggestions?

    There’s many reasons why it might not work.

    I actually heard there is a problem with php’s latest Net-SMTP module, although it should of been patched.

    You can try this from a shell:
    /scripts/autorepair net_smtp_fix

    Additionally, if you have a firewall, make sure it’s not blocking local SMTP.
