SMTP permission denied #13

[Coachonko]

On stable 1.3.0

I want to move away from using PHP's mail function, I want to connect to a SMTP server using port 465 with TLS.

I enter SMTP server, username, password, encryption and port according to the mail server requirements, but when I test the configuration I get the following

Connection could not be established with host mail.domain.com [Permission denied #13]

Note: mail.domain.com is a placeholder to ask for help here, the configuration I entered is correct but it does not seem to work.

The mail server is not blocking my thirty bees server, my thirty bees server does not have any ports blocked. I believe this problem is specific to thirty bees. Where can I find more information about this error? I don't see it in the logs in the logs directory and it does not even appear in the php-fpm logs.

What can the problem be?

it can be... a lot if things. I dont think this is application issue, looks like env misconfiguration problem. For example:

O my god... I had completely forgotten about the selinux booleans. And that was the problem. `sudo setsebool -P httpd_can_network_connect on` fixed it.

This is not the first time it happened. They're always too far in the back of my mind. Thank you for reminding me
