sendmail, 4th Edition

FAX_RELAY mc Macro

At many sites, faxes can be sent via email. When the host that dispatches those faxes is not the local host, you need to relay fax mail to the host that can dispatch faxes. This ability is enabled by defining that relay host with the FAX_RELAY mc configuration macro:

define(`FAX_RELAY', `relay_host')dnl

This causes all mail that ends with the pseudodomain .FAX to be forwarded to relay_host.

On the fax relay machine, you will also have to declare the fax delivery agent with the MAILER( ) mc command (MAILER( ) m4 macro on page 590).
