We are running SBS 2003 with exchange 2003
The problem I am experiencing is as follows:
our company domain name is handled by our isp and they have set up the MX record to point to our exchange server with the failover pointing to one of their servers which we pop every 15 mins to collect any mail that has not made it through our own server (i.e. server turned off, rebooting).
As well as handling our main company domain, the isp also handle the domain of our sister company, the sister company is operationg on pop3 email on individual machines collected from our isp.
If an email is sent from the sister company (or indeed any email address handled by this isp, i have some personal domains there) the email is only collected when the pop3 box at the isp is contacted, and not collected by our own exchange server even if the email address is correct to an individual as in AD.
email sent by anyone else comes straight to our exchange server, even if it is sent to anything@ (this mail would be forwarded to the email address assigned all undilivered mail to go to mailbox keith.lees)
I am sure that this must be a simple setup issue on our exchange server but am unable to find the source of the problem.
