Thanks Adam. Of course, it took many hours to get this from you. The
total count of messages was close to 250,000, and my mail server has
been almost useless today. I used this technique after someone (dek
IIRC) in the #qmail IRC channel pointed me to
http://www.faqts.com/knowledge_base/view.phtml/aid/1443
Anyway, it's been running all day with the new smtproute and the alias
entry. Logs confirm the messages are being "delivered." I'm all the way
down to 140,000 queued msgs now. That's after about 7 hours worth of
processing. For future reference, how unsafe is just removing the files
from mess, info, and remote with qmail running?
