<p class=MsoNormal>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.<br>
<br>
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.<br>
<br>
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.<br>
