[hylafax-users] Trying to piece together a email to fax server

[Robert Moskowitz <rgm@xxxxxxxxxxxxxxx>]

I thought I knew how to do this, but the more I did, the less Iknew.  So 
I threw everything out and started reading again.

It seems the practice is to use the rfc822 format of:  
user@xxxxxxxxxxxxxxxxx

The goal is to send the fax to phone number 'number' and have it 
identified as for 'user'.

This requires first using a DNS mx record with a wildcard.  So you would 
have to two DNS records:

fax.domain.	IN	A	1.2.3.4
*.fax.domain.	IN	MX	10,fax.domain.


Then to your sendmail.mc add:

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


But there is no comment on where these are to be in the sendmail.mc file.

but is this right?  You want to run a script for processing the mail?  
Is the above enough?  what of the script at:

And what of spamassassin?  You want it to trash spam, not try to fax 
it.  How do you get spamassassin to run first.  Also some of the other 
spammer tools (if the from address is invalid reject, can't remember 
right now that tool).

I am setting this up for SIP fax systems.  That is faxes on ATAs that 
are either using T.30 over VoIP or T.38 (for ATAs that support T.38).  
So if I get bad guys sending lots of bad stuff, it wastes paper until I 
can set up a blacklist against them.  Not run up phone bills....

Should I allow for a notify back to the sender?  Have the hylafax log 
for the call mailed to the sender (another reason to first check that 
the from is valid).

thank you for your help
