I also meant to mention this yesterday:  What you can do is turn on Relaydelay
with a flag that acccepts all mail.  Leave it that way for a week or
two, then turn off the flag.  It will have populated the database with
all of the triples for email that was sent to all your recipients that
week

Good side.  No delayed email from your regular correspondents.  Bad
side, some spammers will have their triples in your systems, but most
spammers use a random fake from address so their future attempts to spam
you won't match the triples that got stored during the "populate the db"
week.

I'll try to get a few and post them, but swamped today.

Your welcome.  Next time, I'll have a real notebook or have brow beaten
my X server into allowing clone mode.
