Re: You do not have permission to send to this recipient.

Do you have a reverse pointer record setup for your public mail exchanger
record?

Yes this is an NDR that i received after sending a message. Now I was
able
to find an older message he had sent to me and "reply" and that did not
incur
an NDR so assuming it went thru with no problems.

I cannot replicate this error.

We do have problems with a few domains. earthlink.net has been a problem
and another local domain. It doesn't seem to be consistent.

The message yesterday was to a Cisco employee and it bounced with unable
to
relay. We have gone over and over the relay information on micorsoft and
we
do not feel we are relaying. I think it is somehow related to the fact
that
we have an Exchange server inhouse and have an ISP doing the MX and dns
maintenance. Oh and we are using a Cisco PIX 506e which I have seen
articles
related to making changes to it but since it is not consistent, we don't
feel
this is an issue.

Is it only to certain domains?

We have an internal Exchange 2003 server. Our ISP hosts the DNS and MX
record for our mail server. We have done everything we can to make
sure we
are not relaying. Mail seems to go in and out ok but every once in
awhile we
get the above message.

Could it be that larger organizations "think" we are relaying because
it
originates from our server passes to another at the ISP level then
moves it
on? Why is this happening?
