Linux MTA HOWTO

[llbbl]

Internet mail is sent from the e-mail client to the mail server which routes it to the intended destination which will also be an mail server. The protocol by which the mail servers communicate is called SMTP (Simple Mail Transfer Protocol) and the mail server software is known as the MTA or Mail Transfer Agent. This tutorial lists the popular MTA programs used and basic sendmail configuration. Also listed are Mailing List programs and the RFC's (Request For Comments) on which the internet e-mail standards are currently or eventually based.
