Ok...thanks for the greylisting explanation. As far as dealing with the
ISP.....pretty sure I could learn brain surgery before getting an answer from
them....usually they will deal with me after I have proved that I have
exhausted every other known possibility and that the issue is with them.
As far as sending external domain based email...the exchange server is not
involved as far as I understand as it is smtp and pop from the
desktop/outlook.
Below are the delay and fail receipts............
Reporting-MTA: dns;smtp.nexicom.net

Greylisting means that it won't accept it the *first* time, but the second.
time that you try and deliver it, the message will be accepted, not NDR'd.
Can you post the full text of the eventual NDR that you receive? Have you
checked to make sure that your ISP has PTR records set up?
Where exactly is Exchange involved on your side? It sounds like (from what
you wrote) that the clients (Outlook) are configured with your ISP's mail
server.

Thanks for the reply Andy....just so I understand...greylisting in my case
would be the recipient (hotmail, sympatico) won't accept mail from my ISP
because there have been no successfull deliveries from my domain?
If I am correct...there really isn't anything I nor my ISP can do about
this?
As a note...our previous ISP never had issues like this....is this common
now?
...just another reason I should be hosting this all myself...

if you're getting a 4.4.7, it's most likely a greylisting scheme by the
recipient MTA.

Windows and Exchange 2003
Outlook 2003
Symantec Enterprise 10 for Exchange
We host internal email and pop/smtp domain email from ISP. Settings
for
smtp are those of the ISP. For certain domains (hotmail, sympatico,
ect)
emails are delayed 4.4.7 and then non deliverable. Other domains are
fine
and even appears sending to problem domains is somtimes intermittent.
Scanning outbound mail by Symantec has been disabled and we smtp/pop
from
the desktop.
Is this my issue or our ISP's?????...I can't find anything on my side
causing this and the error states the ISP's smtp server.
Any help or direction is appreciated.
Christo.
