Exchange people, help please!

[dmurray14]

Ok guys,

I'm back begging for some Exchange help! I upgraded to Exchange 2003, which has been both good and bad (ever since the upgrade, outlook now "synchronizes folders" all the time, never instantaeously like it was - but thats not the problem). Anyway, since I installed it, none of my messages are getting past the mail abuse filters. Previously, I took care of this by adding my ISPs SMTP server as the smart host. Unfortunately, though, that doesn't seem to be working any more. I added it to the SMTP protocol, but I still get messages returned with my IP address being listed as rejected, so it's obvious that it's not using the ISPs SMTP server to send the messages. What gives? Any ideas why its not going through the smart host, and any idea how to fix it?

Thanks so much,
Dan

Which server is sending the rejected messages? Is it your SMTP server or your ISP? Post a copy of the undeliverable message here. Have you restarted the SMTP service?

You might want to try the software/apps forum, might get a better response over there...

I tried restarting...that didn't help. Here's the error message:

Well, this is pretty self explantory. You've setup your exchange server to use RBL's and your on one (probably since your coming from a dialup or dsl/cable address). You'll need to either allow your IP's for sending or use something like SMTP auth to authenticate before sending.

That's an Outlook 2003 option and can be configured on the client side; has nothing to do with Exchange.

Actually Bill I'm guessing the address he has listed first (xxx.xxxxxxxx.net) is the recepiant mail server and the mail server sending (xx.xx.xx.xx) is his Exchange server's IP address (or hostname). If this is the case it means he hasnt setup his exchange server to use his ISP's SMTP server correctly; if he had than the recieving server would probably be accepting it (it's unlikely that rbl-plus.mail-abuse.org has his ISP's mail server listed as an open relay).

Dmurry fix your SMTP settings and you'll probably be fine.

I presumed he wasn't using his ISP and was trying to send via his own server.... I think he needs to clarify his setup some more. We need to know if xxx.xxx.xxx.xxx is his smtp relay address or his home address (or something else)...

The way I understood it is that he has his Exchange server on a Comcast IP, and Comcast IPs, by nature, are a lot of times blacklisted because the whole range gets blacklisted or because of previous abuse on that IP.

Pretty common occurance with DSL/Cable when you haven't owned the particular IP for a long time.

I chatted with him a few minutes on AIM about it, the smart host isn't sending it right out, even though I think he had it right.

It works a little different in 2003, so I said to try to make a reciepient policy for *, which would try local delivery of all mail, then forward unresolved hosts to the different server.

Still have yet to hear if it worked or not.

Thanks again mystic...unforuntately I'm having trouble making a policy for *. I can't figure out how to tell it it's for everything...and there's no place to just type *. I'm an exchange idiot, what can I say ...I'll keep poking around...
