This isn't really the answer I was looking for!

This isn't really the answer I was looking for!
Probably I haven't expressed myself well...

This is what I wanted to ask is:
What is a Mail Transport Agent?
What is it for?

Short answer: no, you don't need an MTA.

Long answer: an MTA is often referred to as an "smtp server". They're the real backbone of the email system. When you connect to, that server is running an MTA, which connects to another MTA whose address corresponds to the part of the destination email address after the at sign. This MTA then files it somewhere where the recipient can pick it up (whether this be by POP, IMAP, or simply by using a shell on the server).

Thanks... I gonna uninstall it immediately...
But if MTA is something that an ordinary user would never use why distributions like Mandrake (that should be desktop oriented) keep installing Sendmail & Co. ???
Even the Debian BASE system installs Exim!
How comes that?

I usually leave the MTA on with local delivery only, if asked.
Some programs like to send messages this way. usually to the root user. Cron for example.
