I'll start with the set up:
SBS 2000 Running Exchange using the Pop3 Connector. All of our mail accounts
are offsite pop3 accounts that exchange harvests the emails from.
The Problem:
Up until last week my users were able to email to any domain. Starting last
Friday, everyone in the office now gets the following error when trying to
email to somebody@isp.com :
" Your message did not reach some or all of the intended recipients.

The following recipient(s) could not be reached:

You do not have permission to send to this recipient. For
assistance, contact your system administrator.

I've searched google and Microsoft and it seems that MOST people claim this
is a Blacklist issue. I find no evidence that indicates we are blacklist,
nor can I understand why we would be since we aren't the ones who host our
email. It would appear from the instantaneousness of the error mail being
returned that its not even getting out of our office. The headers are
cryptic mush:

My MAIL provider claims our ISP (yes, yes I know....I'm working on it...) is
at fault, and the ISP claims the MAIL provider is, and I don't think either
one of them have a clue. Can somebody please tell me where to start looking
at what may be broken? We can send email to pretty much anybody else at ANY
other domain, but all emails to the ISP domain get bounced back or it seems
not even out of the office.
I'll take any advice at this point.
Thank you.
