I'm not sure whether or not PMDF-FAX meets your requirements for "faxes
through e-mail"; perhaps I'd best just say what it is that PMDF-FAX does
do.

PMDF-FAX is a set of channel programs for PMDF that provide facilities for
converting text, PostScript, and various other formats into Group 3 FAX,
as well as a set of programs that take these Group 3 FAX files and use
them to drive a variety of FAX modems. Facilities for receiving FAXes from
the modems that are capable of FAX receive and conversion of these materials
into various formats (PostScript, TIFF, GIF, PCL, etc.) are also provided.
Received FAXes can be printed, delivered to files, or automatically forwarded
on as mail messages.

None of this really involves "faxes through e-mail", however. PMDF-FAX can
and has been used to convert mail messages into FAX images which were then
sent via e-mail to another sort of FAX gateway, but usage of this sort is
quite rare. Most people want a way to convert mail messages into real
FAXes and vice versa, and that's what PMDF-FAX is aimed at.

MIME is used throughout to provide type information, multipart facilities,
and so forth. PMDF-FAX was developed with MIME in mind from the outset.
Tricky stuff like automatic defragmentation of message/partial objects is
supported and works quite well (this is actually a feature of PMDF rather
than being specific to PMDF-FAX). And of course the MIME transfer encodings
provide an effective means of dealing with binary message bodyparts.

All of this functionality has been available for some time in the form of
a commercial product -- we released a fully MIME compliant version of
PMDF and PMDF-FAX right at the time MIME appeared as a proposed standard.
Of course development is ongoing: a new version of PMDF and PMDF-FAX is
currently in field test, and it displays the usual feature-creep you'd
expect (support for more formats, better conversion facilities, improved
PostScript fonts, support for more modems, etc. etc. etc.).
