I'm stumped on this one... the process just dies, and leaves nothing particularly revealing in /var/log/mail.log

If it crashes, there might be nothing in /var/log/mail.log but there might be things in /var/log/mail.err, did you look there?

You could also try launching postfix manually with the -D flag to see if there's any interesting debug output.

Anything in /var/log/messages or /var/log/syslog around the time of failure?

Without more details of exploration it could be anything from the out-of-memory (oom)-killer stopping the process, to logrotate not restarting the service.

I once had a mysterious problem with postfix and it turned out to be due to a misconfigured DNS setting. This is probably not your problem but you can try to use strace to help you debug any mysterious problems.
