What ports does outMail use?
What SMTP ports does outMail use?

Solution

This knowledgebase articles details the port that outMail uses to receive connections from its users.

By default SMTP email is sent using TCP Port 25 but some network providers redirect port 25 to their own servers or simply just block it from sending emails not in a registered domain to them.

outMail supports the SMTP Standard of Port 25 and also the standard Messaging Port TCP 587. As some mobile network providers block and redirect both ports outMail provides in addition TCP Port 2525 and 8025 for use with outMail and sending emails.
