Transmission reports are not delivered to distribution lists when Small Business Server 2011 (SBS2011) is used as the SMTP server. Also, clicking the Send Test Email button in GFI FaxMaker configuration > Email2faxGateway settings results in the following error:
Sending test from 'firstname.lastname@example.org' to 'email@example.com' failed. 0x8004020F, The server rejected one or more recipient addresses. The server response was: 550 5.1.1 User unknown
- GFI FaxMaker 2011 for Exchange/SMTP
- Microsoft Small Business Server 2011
In SBS2011, Active Directory distribution groups must be created in the ‘MyBusiness’ organizational unit. Otherwise, Microsoft Exchange will reject SMTP connections.
Ensure that the recipient of the test is part of an Active Directory distribution group in the 'MyBusiness' organizational unit.
