Mac Mail - Tiger 10.4 - Default Port - Setup Guide

Are you using the latest version of Apple's Mac OSX?
Please see our Yosemite 10.10 Mac Mail SMTP server setup guide here.

Important Points

  • First you need to make sure the email address(es) you will be sending from have been authorised for your account in our Control Panel .
  • These instructions assume your email account has already been setup and is collecting email correctly.
  • Take a note of any settings you change.
  • Only change the items specified - you should not need to change either your email address, POP3 server, POP3 username / password.
  • We have instructions for both default SMTP port and alternate SMTP port configurations - alternate port is generally used if your ISP blocks the normal port 25 SMTP access (as many do these days!).
