im trying to enable e-mail alerts on my solarwind server but the problem is that my solarwind server cant contact the smtp server for some reason? whenever i try to telnet on port 25 the smtp server it fails , while i can telnet other devices from my solarwind server , at the same time i can telnet on port 25 my smtp servers from other devices , so that leaves my solarwind server and my smtp server that cant contact each other for some strange reason?
