I currently have Postfix installed and running, but i can easily change to Exim or Qmail. Sendmail isnt really my thing... This is the most troublesome thing for me, none of the online examples for these MTAs worked.

I have just upgraded to Hylafax 5.0.3 and it is working fine as a deamon, i have to be able to initiate the calls to test.

Ill try your mailtofax script as soon as i get the MTA correctly configured.


Thanks


Diego

Okay, but that posting doesn't have anything to do with MTAs or
mail-to-fax stuff.  That information comes out in the reader comments
below, and I would be extremely cautious about expecting the reader
comments to be particularly good or accurate.

There seems to be some misunderstanding on the author's part that
HylaFAX itself can do what he seems to be regressing to Asterfax and
that email2fax script to accomplish... which takes HylaFAX out of the
loop and is effectively a less-capable manner of doing it.

I think that the best way to accomplish what most people want out of a
mail-to-fax arrangement is to use HylaFAX+'s faxmail (faxmail got an
overhaul that is available in 5.0.3).  However, if you have a customized
mail format that you want to use then you may do best to write a faxmail
replacement in shell or something like I've done for RelayFax here:

Okay.  What MTA are you using?  You'll need to instruct the MTA to send
all mail destined to just numbers to the mail-to-fax processor.

If you were using sendmail I would recommend that you create a
fax-specific hostname for mail-to-fax mails... like
"fax.mrcorp.com.mx".  So the fax mails will get sent to
FAXNUMBER@xxxxxxxxxxxxxxxxxx  You'll need to work your DNS in order to
accomplish this, but it makes the sendmail configuration much more
simple.  Then you just set up a virtual user table (file
"virtusertable", usually in /etc/mail) with the entry:

  @fax.mrcorp.com.mx mailtofax

Then run "make" to build the virtusertable.db file.  Then create a
"mailtofax" alias in /etc/aliases that looks something like this:

  mailtofax: "|/usr/local/bin/mailtofax.sh"

Then run newaliases.  If your sendmail is also running smrsh you may
need to create link /etc/smrsh/mailtofax.sh -->
/usr/local/bin/mailtofax.sh.  Then restart sendmail.

Then you need to create the file /usr/local/bin/mailtofax.sh.  You can
do *anything* with it at that point, but I would suggest something like
this:

#!/bin/sh
cat > /tmp/mailtofax.mail.$$
DESTNUM=`grep -m 1 "^To:" /tmp/mailtofax.mail.$$ | sed
's/^To:[^0-9]*\([0-9]*\)@.*/\1/'`
if [ -n "$DESTNUM" ]; then
    cat /tmp/mailtofax.mail.$$ | /usr/local/bin/faxmail -d $DESTNUM
fi
exit

Of course, you'll need to make that suit your needs.  Make sure to mark
the mailtofax.sh script as executable (chmod a+x
/usr/local/bin/mailtofax.sh).

Lee.
