We have recently installed Small Business Server 2003. The problem I am having is that Exchange is not routing emails to the user accounts as I would expect. We are retrieving our email from a POP3 account. If there is a match on the "Display Name", then the email is getting to the correct mailbox. Otherwise they are being dumped into the "Underlivered POP3 Mail" Exchange mailbox.
I have set up user accounts for all expected users/mail boxes and created ailiases for them, but this hasn't helped.
For example, email sent to (say) firstname.lastname@example.org is not being routed to the Info mail box unless the email comes in with a display name matching the account name. That is, if I send an email to email@example.com it ends up in the "undelivered" mailbox. If I reply to an email sent from firstname.lastname@example.org, then it ends up in the Info mailbox.
What have I missed? Why is Exchange not directing emails to mail boxes based on the email address and and Aliases set up for the account?
Thanks in advance, Sumsol.
