I have installed FAXserve Groupwise Gateway (FAXserve 7.5) on my Growise
7.0 server. While trying to send fax using the addressing format for
example FAX:+1-209-627-4512@myDomain.Gateway then i am getting 550 unknown
host error. The fax is not at all routed to the gateway.

Can anyone suggest me what could be the cause and how to overcome this

Thanks in advance,
