I recently signed up for a remote colo UML with 32MB of RAM. I have it running Postfix as a backup MX, OpenVPN to provide a secure link to the real network, sshd, bind 9, and Apache (1.3). All of my outgoing mail is relayed through the box... thus far no incoming mail has been relayed through it, so we aren't talking very high traffic. With all that running, I'm using 9004KB of RAM and 396KB of swap. My load average sits at 0.00, 0.00, 0.00. Here's the ps aux output for postfix: USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 110 0.0 3.1 2324 900 ? S Feb10 0:00 /usr/libexec/postfix/master postfix 393 0.0 3.3 2340 952 ? S Feb10 0:00 qmgr -l -t fifo -u postfix 983 0.0 2.9 2280 840 ? S 02:17 0:00 pickup -l -t fifo -u So... I really don't think Postfix is that huge. Sure, you can probably get something using only 2MB of RAM instead of this huge 3MB... but why? :-) Postfix is, by most accounts, far faster than any of the less common alternatives, and generally considered more secure. All I'm saying is don't abandon postfix, which works for what you need, simply because it seems like overkill. I really don't think it is. :-) Rob
