outlook is appending my local domain to an email address
Posted on 2009-12-22
I am using Outlook 2003 and exchange server 2003 in my corporate environment. When I send an email to a particular user i get a bounced email notification from my SMTP server that says relaying is not allowed. Now the odd part about this is that the email address that is not being allowed is firstname.lastname@example.org. The email address I am sending my email to is email@example.com. It seems like Outlook or Exchange is adding my local domain to the end of the email address.
I can copy other people in other domains and they get the email, but mrjones email will bounce. When I sent the email to firstname.lastname@example.org and copied my yahoo.com account, the email I got at yahoo says that email@example.com was copied as well. If I click reply all to that email I got in my yahoo.com account, yahoo.com tries to send to firstname.lastname@example.org.
Why is Outlook or exchange or something else appending my local domain to this email address?
