Mozilla Thunderbird v38 - Alternate Port - Setup Guide

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 - do not change your email address or incoming email settings.
  • 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!).
