Outgoing mail through Exchange Server with Pop3 connector

Hi experts,

I have a pretty interesting problem.  We currently use Windows SBS2003 with exchange server and a third party pop3 connector to pull down email from our web hosting company who provide us with email addresses at our domain name.  Inside our office we have six users getting their mail off the exchange server and we have no problems sending or receiving mail inside the company.  We can also send and receive mail from outside of the company with one major exception.  We have four users outside of our office who have email addresses created web host  but do not have user accounts setup on our Windows Server or Exchange Server.  They access their mail from the web host directly though pop3 in Outlook.  We can receive mail from them without any problems but we cannot send mail out to them.  Everything we try to send out to them immediately comes back as undeliverable with the following message:


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

      Subject:      Test
      Sent:      10/4/2004 4:46 PM

The following recipient(s) could not be reached:

      changed_to_protect_the_innocent@internationaltractor.com on 10/4/2004 4:45 PM
            The e-mail account does not exist at the organization this message was sent to.  Check the e-mail address, or contact the recipient directly to find out the correct address.
            <INTERNATIONALTRACTOR.COM #5.1.1>


I am baffled by this and am in no way an expert in any of this! Any help would be much appreciated!

If your internal users reside on a server that believes it hosts mail for "Tractor.com", then it believes those 4 external users should be located internally. Thus the message you receive "e-mail account does not exist" ...

Hi BNettles,

I followed the link you referred to above and did as Vahik suggested.  I am now able to send out mail to all users.  However we now cannot receive any mail into our addresses.  The mail just sits on or email host and is not retreived by our pop3 connector.

I'm not sure if this could be an issue with the pop3 connector (IGetMail made by www.lockstep.com), or if the new policy simply hasn't taken effect yet.  I know that sometimes it can take up to one day.  Maybe there is another setting I am unaware of?

Any help would be appreciated.

Best regards,

Ari

You may need to update or rebuild the Recipient Update Service ... are you familiar with this process?

Navigate to the RUS and right click on it ... then select Update ... give a short period of time for replication to occur ... check user accounts to make sure they have been stamped with the new changes ... if that doesn't work then you may want to rebuild ...

Still no luck.  We can send out to any address but can't receive.  Maybe I'm not being patient enough.  Email is sitting on Web host and I double checked the pop3 connector and everything is connecting fine.  It's just not putting the mail where it needs to go.  At least we aren't losing our mail into the abyss.  Any ideas?

Thanks

Of course I thought I could get away without restarting!  I guess not.  Works now.  Thanks for your help!

I'll award you the points and close the question.

Best regards,
