Hello,

I've been running postfix for a few months now and things have (for the
most part) been pretty great. But in the last month or so the local
delivery agent just stops sending mail. smtp still works as we can send
mail out, and postfix is still accepting mail as well. It's just
getting hung up in the queue. I thought it might've been a problem with
and older version of amavisd-new but I updated it and still had the
problem today. I looked in the logs but didn't see anything out of the
ordinary except for sometime around 3:15am is the last postfix/local
message. One thing to note is that we do have some backups that run at
3am but it's not doing anything but a bunch of IO work. So the load
probably increases a but but that shouldn't stop the mail? Plus the
backup runs every night and this only happened three times in the last
month but I'd like to fix this as I'm starting to get those "this never
happened with the old email server" comments. :)

Postfix 2.0.9
amavisd-new-20030616-p2
Spamassassin 2.55
courier-imap-1.7.2 (I use maildrop instead of procmail)

And just for reference, here's a 'postconf -n':

alias_maps = hash:/etc/postfix/aliases, hash:/home/mailman/data/aliases
