Actually, it looks to me like that just lets Sendmail process the mail 
being held in mqueue. The problem is, there isn't anything there. If I 
understand this correctly, it is MailScanner that takes the messages 
from mqueue.in and moves them to mqueue, which is the part that isn't 
happening.

I tried to modify the "start" section of /etc/init.d/MailScanner to 
start both the outbound Sendmail and MailScanner, but that wasn't as 
simple as I hoped. Right now I'm moving massive chunks of mail from the 
mqueue.in (and backups thereof) into mqueue, then using the "startout" 
option, which is working. Tedious, but it's working.

Of course, if Hotmail has another million messages for me when I start 
the standard MailScanner back up I don't know what I can do about it.
