LinuxCBT Mail Edition focuses on the 3 leading Mail Transfer Agents (MTAs) and ancillary components:

Sendmail - LinuxCBT Sendmail Edition
Postfix - LinuxCBT Postfix Edition
qmail - LinuxCBT qmail Edition.

Linux/UNIX systems are responsible for moving the overwhelming majority of electronic mail across private and public networks. Consequently, savvy Systems Admins. are expected to have a solid foundation in MTAs and ancillary components for general and automated mail-based applications.

Let LinuxCBT Mail Edition help to solidify your understanding of key MTAs and ancillary components.

Hey,

Can you please re-upload part 1 of CD 2.

www.megaupload.com/?d=2ZITVGZY

This link is not working. All other links are working fine now

Fantastic post!

But, could you please re-upload part 1 of CD 2.

It states that it is temporarily unavailable, yet I have waited for a while.

I have all the other parts and don’t want to waste all that bandwidth.

Cheers,
Mike
