I've been trying to use sendmail to send a fax from a UNIX server via an Esker fax server.
If I set the reciepient address to the email address of the fax server plus the fax number a fax is successfully generated, but any attempt I make to specify a fax template and fields to populate such a template fail.
I believe this is probably a configuration issue on the Unix Server.
Any advise on how to resolve this problem would be appreciated.
