OK folks... New filter is available
ftp://ftp.exim.org/pub/filter/
or
http://www.exim.org/system_filter.exim
Install/usage instructions are in the file.
The "active" test is:-
if ${length_80:$header_date:} is not $header_date:
then
fail text "This message has been rejected because it has\n\
\tan overlength date field which can be used\n\
\tto subvert Microsoft mail programs\n\
\tThe following URL has further information\n\
\thttp://www.securityfocus.com/frames/?content=/templates/article.
html%3Fid%3D61"
seen finish
endif
but my mail client line wraps, so be careful.
If you roll your own remember that this one will work if put in bounce
messages too!
The MD5 checksum of the whole filter is
dacb44e417ac0f494e62c32220cdd209 system_filter.exim
If someone can suggest a cleaner way to test for a string/header being
longer than n chars please let me know.
Nigel.
