Malformed RFC822 headers - continuation lines not indented

2002-01-26 10:36:57
All:

A while back I seem to remember there was some brief discussion of a
worm that was generating malformed RFC822 headers, specifically having
continued header lines that were NOT indented properly (I assume in an
attempt to bypass strict security systems to attack forgiving mailers,
though stupidity may also be the cause).

For example:

     Properheader: blahblahblah
             continuation line properly indented
     Malformedheader: blahblahblah
     continued header not indented
     another unindented header continuation line

I've been poking around but I can't find this in my archive of
interesting list postings that I've kept.

Does anybody else remember this?

Question: does procmail deal gracefully with RFC822 headers malformed
in this manner?

Request: does anybody have a real-life sample of one of these that
could be gzipped and sent to me?

Thanks!
