Outbound e-mail issue with Exchange

[Daniel Jaburg]

I'm having an unusual issue with a client and I'm not sure how to resolve
it. The client has their POP3 mail outsourced, but wanted to have Exchange
2000 running on their local server to handle calendaring. Each client is
running Outlook 2002 and has their exchange and pop3 accounts runnig on
their computers. If the Exchange account is selected as the default
account, then any e-mail sent to the outside passes through the Exchange
server and e-mail gets rejected by any host that uses reverse dns to verify
the sender. If the POP3 account is selected as the default account, then
any messages sent to anyone in the company gets two messages, one via pop3
and the other from the exchange server. It seems as if any e-mail sent
regardless of sending account passes through the exchange server?
Ultimately, I'd like to have it setup so that everything passes via the pop3
account to prevent this from happening, but the only way to do that is to
remove the exchange account, which then prevents them from using their
shared contacts and calendaring. Any ideas?

You might want to talk to your mailhost/ISP and see if you can have them
relay email from your Exchange, they will be able (or should have) set up a
reverse DNS for your Domain and you will need to set up a Smarthost in
Exchange (usually dont like this but as you are using an outsourced mail
collection). Alternately you can go the whole nine yards and use Exchange
for collection and sending.

I'm going to try setting up the smarthost to see if that works...thanks.

So far so good with the smart host change and their domain host doesn't mind
since those e-mails should have gone through them anyway. Again, thanks.

Glad you got it working
