While Eric's way of doing things works, I reccomend asking your systems manager to look at installing procmail as the Mlocal agent. This is good advice, for different reasons. I do realize that the stated reasons in the little tutorial were for mail sorting, but I really worked it out for remailer addressing. Installing procmail for local delivery does make filtering easier. The idea is that I could, for example, take an address, for example hughes+SOLONg@ah.com, which is really addressed to someone else, and map it in my own mail filter, at the user level, to the real recipient. This address is a real first class address, not just a comment in an address field, and is guaranteed to work wherever email is supported. Now as far as politics go, I wrote that tutorial in such a way that you could give it to your sysadmin and have them do the work. The "explanation" at the beginning is a prepackaged excuse for why you want it. ;-> Eric
