i'd suggest postfix + cyrus. from comments in the postfix-users list, it seems to be a nearly ideal combination for doing what you want. both are packaged for debian. postfix is at http://www.postfix.org/ URL for cyrus should be in the package's documentation. i haven't used cyrus, but i'm a big fan of postfix - wouldn't use anything else these days, and i've tried all of the available MTAs over the last 5 or 6 years. hint, for performance you probably want to look at a machine with multiple fast scsci drives for the mail spool (raid striping), formatted with reiserfs. and lots of memory, of course. CPU speed isn't a big issue - mail systems are I/O bound. craig -- craig sanders
