I used Post.Office for almost 4 years; so I became quite
familiar with their product and support before moving on
to other things (better job).

In regards to their spam relay prevention, I found
out that their mail relay prevention implementation
(IP address based and domain name based) doesn't work properly.
Their implementation can easily be gotten around
(no spoofing is required.)

If you run Post.Office, you are probably going to be used
by (the smarter) spammers unless you have some other mail
relay-blocking mechanism in place.
