Topic: restrict outgoing connections for my mailserver

First:
Thank you very much for iRedMail!! smile

Hi,
is there any documentation which lists all outgoing connections?

For example:
Allow outgoing port 80 + 443 to http://spamassassin.apache.org/updates/MIRRORED.BY and the listed mirrors in MIRRORED.BY
Allow outgoing port 80 + 443 to https://raw.githubusercontent.com
Allow outgoing port 80 + 443 to https://github.com
...

I want to restrict all outgoing connections for my mailserver, except port 25 ^^ if possible.


Thank you + BR
schtebo
