I have my own epost server hosted on linux Debian
with postfix and Dovcot
My epost clients is Microsoft outlook 2015
I work a lot with customers or elsewhere.
I experience up that email my not work because SIP / network admin has sprret port 25 (SNMP) to that I must use their SMTP server to send mail.
I've tried to open my server with 2 ports. 25 and 9800 it did not solve the problem.
I'm tired of having to change smtp server and ports to like that all tidne
Anybody know a fix ??
or must I go over to webmail or Exhange server?
