Contents of the mail log when the failure happens would be good also the php log may help

[jimr1]

This is at the point roundcube issues the error ?

[cubanxp]

Yes is the only log i see on there.

[jimr1]

What about php error log ?

[stefan1959]

you should see a postfix connection or error for roundcube.

From the config.

[cubanxp]

Nothing in the php error log.

Hello, i found a solution for my problem online change port to 25 and add this:

SMTP server does not support authentication so you should set:

$rcmail_config[‘smtp_user’] = ‘’;
$rcmail_config[‘smtp_pass’] = ‘’;

Thank you. for the support.
