New installation of 2003 server all relevant updates carried out. Exchange configured to download mail from mail server using pop connector. Sometimes (and this happens randomly) a users email (usually only 1 email) will get redirected to the administrator which is set as the account for non existant email addresses. Therefore this is what you would expect if the email address is incorrect, however, there is nothing wrong with the email address details. This is happening randomly for various users. Any help would be appreciated.

Ok, I did some more digging now that I know I'm not crazy, and came up with an Exchange Store Rollup Patch from Apr 19, 2004 that fixes a bunch of things...

http://support.microsoft.com/?kbid=838236

I didn't see anything specific about your (my) problem, but I just scanned the fixes, didn't read in detail... anyways, recognized other problems we're having at a few sites and am going to get busy installing it...

Good luck.

I've applied the patch you spoke about, the fault is still apparent, I'm considering contacting microsoft next unless anyone else has got any suggestions?

Update to this problem, I've monitored the emails being re-directed and they seem to be mainly bulk emails or read receipts, could this have a bearing on the problem?

I've asked people who have sent me email that end up in the Administrator's mailbox, and got a variety of answers (single recipient, with or without read receipts, with or without attachments) ... doesn't seem to be a pattern.

I now have 6 installations acting this way.

BTW, the patch did nothing for me either.

There is a new POP patch on the SBS update site which I applied 2 days ago to 2 sites. So far so good. I have had a couple of the people who I was having trouble with email me and their messages were delivered correctly.... I'm hoping this fixes the problem...

The patch is here: http://www.microsoft.com/downloads/details.aspx?FamilyID=7b1ff109-092e-4418-aa37-a53af7b8f6fc&DisplayLang=en

good luck...

tried the pop connector patch and the problem is still apparent, back to the drawing board.  amayhew, thanks for your suggestion, but this actually defeats the object of installing SBS if a third party pop connector software is then installed. I'll put this one to microsoft and see what they come up with. GearyTech, are your problem systems definitely fixed? if so I'd be interested to check all the actions you have taken, I may have a different config to you, or, may have missed something.

MJD,

I have been able to minimize the effect of the problem at one site by defining some rules within the POP connector... that is to say, I have specifically stated that if the To or CC field contains the name of the recipient (first name, first name last name, Alias) then redirect it to the user's mailbox. This has solved the problem in one case.

In another case, I changed the ISP to one that gives us a static IP and got rid of the POP connector all together.

In yet another case (the customer is on cable), I put the CName of the ISP's modem into the MX record and forward all email to that CName, therefore bypassing the POP connector. This fixes the problem of having only a dynamic IP from this ISP.

And, in yet one more case, I created a DNS alias for the customer and forwarded that alias via the MX record. In this case, and the one above, I had to get a 3rd party backup MX record in the event the ISP went down, or in the event the DNS alias didn't catch up fast enough to catch mail.

Things are better... good luck with yours!
