Hi, I am a very new user trying out Astaro for my home network on an extra PC. I can send out email on port 25 from Thunderbird but if I try to use my outgoing smtp server's alternate port, I believe Astaro is blocking it. If I bypass the Astaro server, sending on the alternate port works good. I am not running the SMTP proxy. I cannot find any setting to change on the backend to allowing outgoing smtp on other ports (I cannot find anything allowing smtp on port 25 either).
