Non-working mail_daemon if there's no network when it starts

[humdinger]

This is hrev54487.

At least that's what I guess. I suffer from the intel_extreme driver sometimes taking a minute or two until my screen comes alive. After it does, I often have to connect manually. The mail_daemon was started long before that, of course.
In this situation, checking for new mail doesn't work. I have to restart the mail_daemon manually (tip: hold SHIFT while right-clickin the mailbox to get a "Shutdown mail services").

No clues in the syslog.
