Mail Server Ports

When configuring your desktop or mobile client we have the following ports setup. These will need to be enabled on either a network firewall or the Windows Server firewall itself. Listed below are common ports that are used for mail delivery:

• Port 80 - HTTP traffic and ActiveSync traffic - used to access the web interface of SmarterMail. This would also be the same port used by ActiveSync as well
