I think what he was really asking is 'what is "MTA"' (an email-related thing). In that case, it's the Mail Transport Agent (software that moves mail between hosts using the SMTP protocol). The most common ones you see on Linux are "sendmail" and "postfix". Other pieces of software in the email chain are the MDA (Mail Delivery Agent), which the MTA uses to put mail in individual users' mailboxes upon receipt. The most common one on Linux is "procmail" and the MDA typically runs on the same machine as the RECEIVING MTA. Finally, there's the MUA (Mail User Agent), which is essentially what end users use to view the mail. There's tons of those, but most common I've found on Linux are Thunderbird, claws-mail, mutt, Balsa, KDEMail, etc. Note that it is the MUA that uses protocols such as IMAP4, POP3, MAPI and the like. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital ricks@xxxxxxxxxxxxxx - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - Overweight: When you step on your dog's tail...and it dies. - ---------------------------------------------------------------------- _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
