Err... "per IP" isn't the same as "per connection".

The trouble with "per IP" is that access to that may be concurrent.
There may well be 2 connections from the same IP, both active at the
exact same time.

If you really want to do that -- handle per IP connections -- I'd
suggest to use a real database, preferably one that has an "inet" type,
like postgresql. You may even want to consider storing IPv6 info per /64
and possibly IPv4 info per /24, depending on your needs.

If, however, you really meant "per SMTP session" information, for
example to remember state between "RCPT" commands, then David's
suggestions are perfect. Particularly, do look at "MAINTAINING STATE" in
the manual.
