I am sending some email with a plain SMTP server and have unique IP's. What port is best to use, port 25 or port 26 ? I am a noobie so sorry for the stupid question!
Isn't port 25 the normal smtp port and 26 is the ssl one? Well thats how it is configurated on cPanel.
I hear if you send on port 1337 there's a loophole in yahoo, apparently their cisco router's management uses that port so it automatically allows all traffic..
