Outlook users are receiving non-delivery error messages when sending fax emails:
550 5.1.1 email@example.com User Unknown.
The e-mail address of the recipient was not found in the e-mail system of the recipient.
Delivery has failed to these recipients or groups:
"firstname.lastname@example.org (email@example.com) <mailto:firstname.lastname@example.org> The e-mail address you entered couldn't be found. Please check the recipient's e-mail address and try to resend the message. If the problem continues, please contact your helpdesk."
- GFI FaxMaker
- Microsoft Exchange 2003
- Microsoft Exchange 2007
- Microsoft Exchange 2010
The Exchange server was assigned authoritative rights to the faxmaker.com domain and it was looking in its own MailBox server for a user with the e-mail address "email@example.com", and since it could not find one it was generating the non-delivery report.
In other words, if faxmaker.com is listed as an accepted domain in Microsoft Exchange Server 2007 / 2010 the Microsoft Exchange Server starts to search for the local recipient firstname.lastname@example.org instead of delivering the fax email request to the GFI FaxMaker server.
