How to enable SMTP on port 25 for whitelisted IPs

Postby klik333 » Tue Sep 22, 2020 3:17 am

Hello, guys!
Is it possible to enable port 25 (without TLS) for sending messages from certain IP ?
Now I can connect to port 25 only from my local network, but I would like to add the same opportunity for one of my external server.
I've added my external server's IP to zimbraMtaMyNetworks parameter, but it didn't help.
Please give me a hint if you know the subject.
Thank you.

Hello,

in my opinion this is not a zimbra but a firewall/router issue...
You'll have to look at what you have between your zimbra server and the internet and start there.
