All,
I've posted FOOTER32, a Declude Junkmail add-in that can add footers
to both text/plain and text/html MIME parts. Development was triggered
by an IMail user's request to add legal disclaimers to all outgoing
messages (currently impossible with vanilla IMail/Declude), but the
tool can certainly be used to add footers for other purposes.
Installation is simple: FOOTER32 is a Declude external test with
(typically) a weight of 0.
Configuration is by means of a few basic command-line switches:
- Like our SPAMC32, FOOTER32 offers the option to have a skip-if
weight (-sw switch) so that it will not be run if the message has
already achieved a predefined weight (if the message is going to be
quarantined or deleted, there may be no reason to add a footer).
- Maximum message size (-a) for rare occasions when processing power
is very limited and you don't want to parse out and rewrite very large
messages. This will certainly not be workable for legal disclaimers,
but could be for other uses.
- Footer file (-yf) allows you to specify the text file that contains
your footer text. Different hosts can have different footers, or none
at all, by passing the Declude %LOCALHOST% variable on the command
line.
- No-footer file (-nf) allows you to specify the signal file (can be a
0-byte file) that will turn off a disclaimer for selected hosts. This
is helpful if you are using a single shared footer file for all hosts
except a chosen few.
- Outgoing-only (-oo) only adds footers to outgoing messages, using
the Declude %INOROUT% variable.
Operation is by means of simple insertion within MIME assembly:
- Text body parts have the contents of the footer file appended
verbatim.
- HTML body parts have the contents of the footer file appended in a
fixed-width font, with HTML entity codes substituted for
carriage-return and space characters. This allows for full-justified
footer.txt files to be appended in a businesslike, neutral format.
There are currently no plans to change this behavior -- FOOTER32 is
designed to adapt plain-text footers to plain-*looking* HTML footers,
not to provide a design platform for fancy signatures!

Notes:
- Support and feature requests will be through the Declude Junkmail
list.
- The usual disclaimers about modifying message bodies in transit
apply (PGP, iCal, etc.).
- Badly malformed MIME messages will cause the tool to exit
harmlessly, but without adding the footer. You can forward unaltered
messages to me, and I'll see what I can do, but that can be a can of
worms: this isn't a security application, so working around
non-standard mailers was far from a priority. The main goals here were
(1) to reliably add footers to rich-text messages created by
RFC-compliant mailers, (2) to show "good faith" in attempting
modifications to broken messages, and (3) and to degrade gracefully if
unsuccessful.
Enjoy!
