Sorry for this very basic question: How do I setup SMTP on the server - in webmin?
I have a VPS with a few domains. I run Postfix.
From the PC I use my ISPs SMTP. But from the phone it doesn't work because of different network. I don't want to try the phones settings because then I guess I guess it will not work when on WiFi, or out of phone companies reach.
I am not sure if my ISP/phone company block Port25 - how can I test that?
I believe my domain has a (one) domain entry (mx.mydomain.com) that functions as pop and smtp.
What I like it:
• Send my email via mx.mydomain.com • Have it setup that only mail with **@mydomain.com is accepted • Have some sort of security so people can't spoof **@mydomain.com as sender and use my MX to SPAM.
Any advise will be appreciated greatly!
