Alan:
One of the problems with that approach is that, for a variety of good
reasons, sometimes a user can have different email addresses with
different domain extensions that don't match the sending ISP portal.
For example, my local ISP is dejazzd.com. and while I have email
addresses that end in @dejazzd.com, I also have addresses that end in
@ptd.net and @we-buy-books.com that I append to emails that I send
through my local ISP (dejazzd.com)
I understand the need to stem spam but the tighter you restrict your
rules, the more that legitimate mail gets throttled.
