Sendmail Mangling for HylaFAX faxmail

Faxmail is quite handy to fax a short notice to somebody who does not have an e-mail account. Or the other way round, have your own received mail forwarded by fax to yourself somewhere, like on your 80 ft yacht :-)

Faxmail is able to handle PostScript and other configurable types of images natively as MIME encoded parts (attachments), but please see faxmail(1) for more specific and better information.

Now, there are two ways to configure sendmail . 

I. You can either  add to your .mc file, that is linux.mc or OS-Type.mc, or to
your .m4 file the following:

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

While the path to faxmail might be different, depending on OS-Type and
distribution, the arguments can be taken from man (1) faxmail.
After adding to your mail.mc or m4 file, you have to translate the
file with the m4 macros. That is 

                # m4 mail.mc > sendmail.cf

II. Or can do it the hard way and edit your sendmail.cf  :-)

Mfax,       P=/usr/bin/faxmail, F=DFMhu, S=14, R=24, M=100000,
                                    T=X-Phone/X-FAX/X-Unix ,
                                    A=faxmail -d -n -p 12pt $u@$h $f

It is quite important tha you do not use the feature allmasquerade in
your sendmail configuration as this feature would include the
masquerading of the domain fax.

The mail address would be something like
                To: joe.brown@0123456.fax
