How do I send POP3 mail through Exchange 2003 from home network?

Hello,

My test network at home consists of a XP workstation, 2003 Domain Controller and Exchange Server. I have communication between all 3 machines. I'm able to receive domain mail and my POP3 mail but I'm unable to "send" POP3 mail. I'm trying to send my mail "through" my Exchange server rather than directly to my ISP, thus the "test network".

My Exchange brothers, please send my a sign....

thanks in advance....

You don't "send" mail via POP3. POP3 is a protocol for *fetching* mail from a POP server.

If you have incoming mail via POP3 sorted, I'll skip comment on that; to get Exchange Server to send mail out, it must use SMTP. You can either have it "hand off" all outgoing mail to the SMTP server of your ISP (most common, and generally easiest to set up) or you can have ES direct-send the mail to the MX host of the domain each mail is being sent to.

Revisit your ES setup and look at SMTP parameters :-)

Also...post the error message if any that you get when sending mail....Maybe you've just got your terms mixed up :)

Thanks for the replies,

This is the error message I'm getting when I try to send mail through my ES.

Your message did not reach some or all of the intended recipients.

Subject: sent from newserver

The following recipient(s) could not be reached:

There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
<exchangeserver.Babylon.local #5.5.0 smtp;550 You are not allowed to send mail. Please refer to www.spamhaus.org, dsbl.org and njabl.org for more information.>

Looks like I haven't configured my Server for SMTP. I'm kinda new to Exchange so bear with me.

Suggestions?...................

Hello,

The error message I get is basically the same no matter who I try to email to. In the instance above, I was trying to send an email to my own personal email. Why is the error saying I'm on a blacklist? If I send directly from my Outlook workstation to my email, no problems.

I've never configured SMTP on my exchange server. Is it set up by default?
I tried sending to another personal email just now and I'm getting this:

The message cannot be delivered due to a configuration error on the server. Please contact your Administrator.
<exchangeserver.Babylon.local #5.3.0 smtp;553 5.3.0 flpvm21,DNSBL:

So far I've tried sending about 8 emails and all but 1 came back with an error.

thanks in advance......

Goto the website of www.sorbs.net. Register for free and then run your IP and or servername via their lookup database. I've gotten the same errors from them. Basically, they host a list of servers that have in the past either been blacklisted or are known to be open relays or send spam. The sad part is that they are not an authoritive service, so they actually don't have any say about such matters. (IMO). But that ain't the real problem. It would appear that more and more Spam filters are using the sorbs database as an authorive list for all blacklisted sites/servers. Their websites states that the only way that you're gonna get off their list is to pay a US$50 "fine". But go check out their database lookup, It should tell you the exact reason, ie. on of the servers that I checked out, it was refering to mail that was sent 17 July 2004, even showed me the subject of the offensive mail.
