Exchange email delivery problem

I have a user "dispatch@MYDOMAIN.com" who should be receiving emails that are generated from our website when a client fills out a service request form.  Our clients fill the request form on are website, and they are then submitted to "dispatch@MYDOMAIN.com". The emails are sent from "mailbot@DOMAIN.com".

We have a Barracuda Spam filter in place which recieves incoming mail and then fowardes everything that passes the filter onto our Exchange Server 2003.  We have verified that the emails are hitting the Spam filter, and we have also verified that the emails are whitelisted.  The Spam filter logs; state that the mail from "mailbot@DOMAIN.com" are white listed and have been delivered, but they never reach the user's mailbox.

We have also bypassed the Spam filter, and the mail still isnt being delivered.  I have also checked the user's junk folders in Outlook, and also set mailbot's domain as a safe sender in Outlook.

Im running out of idea's and any help would be appreciated.

I would also check the priority of your spam filters.  If the whitelist is lower than another filter, it will block it before it ever gets to the whitelist.

Good luck -

Hi,
I would check the SMTP Log and use Message tracking (under ESM--Tools) to see if the Mesasge infact entered Exchange at all

According to the Message Tracking Center the emails are being received at the Exchange Server.

These are the events that are generated:
                     
                           SMTP: Message Submitted to Advanced Queuing
                           SMTP: Started Message Submission to Advanced Queue
                           SMTP: Message submitted to Categorizer

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

There isnt anything after the Categorizer.  They aren't being routed, and they aren't going into queue.
