this is normally better suited for the questions and answers forum, but seeing as you will need more info first, here's a BASIC outrline. POST more info as to the OS and Mail server into the Technical Q&A forum to get accurate resopnses.
For inbound mail, depending on what TYPE of mail server you're running, GroupWise, Exchange etc. all you need to do is open the users account and add an ALIAS through the users mail properties tab. No need to redirect, it will assume that name A, name B etc all go to the same account.
As for hiding the senders name on OUTBOUND mail, the easiest (but easily cracked) way to do this is by sending via Hotmail or another webbased mail account. Note: It still shows the IP address, some REALLY SIMPLE digging will give you the senders name, address and phone numbers. A lot of people use online accounts to mask thier identity but it is easily worked around.
Remailers:
Truly anonymous remailers don't offer any way to reply to the sender. There are two main types: Cypherpunk (Type I) and Mixmaster (Type II). These are harder to use than pseudonymous remailers, but they're more secure. You need to learn how to use PGP encryption, build the message, and set up the chain of remailers through which your message is transmitted. Cypherpunk messages can be created in Notepad, but Mixmaster messages require special software.

Hope you find the answers in the Q&A section, but you will need to include your mail system type.
