What is SMTP?

SMTP is short for Simple Mail Transfer Protocol, which is the method used for Internet email delivery. It is the most widely used protocol for sending outbound email from one server to another, known as a SMTP relay. The outbound SMTP server is generally known as a Mail Transfer Agent or MTA.

Prolateral saved the day with outMail when my ISP started blocking port 25.  Very simple signup and excellent how to guides for my desktop pc and mobile device.

The instructions were extremely helpful when setting up my Apple iPad too.
