Re: SpamHaus & SMTP Authentication

You need to fix the spamming problem of course. I would fix it and try
to get delisted. Or if the ip is blacklisted (dynamic ip, meaning
improperly listed) because the ISP did something wrong then the ISP
should work to solve the problem.

We have just had a problem this morning and can't seem to find the answer so
am hoping someone can point us in the right direction.
We have started having our outgoing mail knocked back due to the fact the
our static IP is now listed in Spamhaus PBL, and requires us to use SMTP
authentication. I can't find a definitive answer of hwo to do this on our
exchange server.
Any help would be greatly appreciated.
Thanks in advance
