[hylafax-users] here is what I did to get sendmail to receive faxes

[Robert Moskowitz <rgm@xxxxxxxxxxxxxxx>]

An old friend of mine has been helping me out with sendmail.  And now it 
is working.  So after pestering all of you here, I will share what works 
for me, and maybe Lee might change the sendmail howto!

The goal is to recieve mail addressed to:  user@fax#.fax.foo.com and 
send the fax to phone number fax# to user.

First challenge is a DNS one:  Set up a pseudo domain.  Note that RFCs 
on sendmail make warnings about pseudo domains.  This is perhaps one of 
the few valid uses of pseudo domains.

Given a host name of the Hylafax server of fax.foo.com create the 
folllowing DNS record:

*.fax.foo.com.   IN   MX   10    fax.foo.com.

Next are changes in sendmail.  In your realy-domain file add the line:

fax.foo.com

Append these lines to your sendmail.mc file:

define(`FAX_MAILER_PATH',`/usr/bin/faxmail')dnl
define(`FAX_MAILER_ARGS',`faxmail -d -n -p 12pt $u@$h $f')dnl
MAILER(`fax')dnl

make the sendmail.cf file and edit the line:

R$+ < @ $+ .FAX. > $#fax $@ $2 $: $1 user@xxxxxxxx

to

R$+ < @ $+ .fax.foo.com. > $#fax $@ $2 $: $1 user@xxxxxxxxxxxxxxxx

Customize from this point to your needs.

To avoid having to edit sendmail.cf ever time you change sendmail.mc you 
can edit:

/usr/share/sendmail-cf/m4/proto.m4      (this is where it is in my 
Centos 5 system)

Then you probably only have to make the changes when you get a bind 
update....

Oh, I have not tested PDFs or other attachments.  The fax is also our 
copier and my wife is using it for a while tonight  :)
