Ever since attempting to upgrade/move Exchange from 5.5 to 2003 my mail has blown up. I thought that it was awful strange that I wasn’t getting any email. I don’t know if it has to do with the Active Directory Connector piece or something else but I see error 421 in the SMTP logs on the mail server. When I attempt to send email to myself from another domain, I get “421 Internal error. Connection closing”. So it looks like I haven’t been getting email since Wednesday. Afer I’m done playing outside, I’m gonna sit down and attempt to figure out what went wrong and fix it.
