Mac Mail - Snow Leopard 10.6 - Alternate Port - Setup Guide

Are you using the latest version of Apple's Mac OSX?
Please see our Mojave 10.14 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.

• These instructions are only for Mac Mail on Snow Leopard 10.6 - for other email programs please see How To Setup AuthSMTP or contact us.

• 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!).
