From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux 2.2.19-6.2.1 i686; en-US; rv:0.9.1) Gecko/20010607 Description of problem: The formail binary from procmail 3.14-2 tries to "clean up" message headers that contain whitespace between the header name and the colon, e.g. "Subject : test" becomes "Subject: test". But it does this for all lines, even within the body of a message. It should only do this sort of thing to message headers. Data corruption of course is rather evil. PGP-signed messages may be rendered unverifiable. Source code or other important data sent via email may be rendered unusable or even dangerous. How reproducible: Always Steps to Reproduce: 1. printf 'Subject: test\nTo: test\nFrom: test\n\nhere is text\nNotaheader : this is a body line\n' | formail -f Actual Results: "Notaheader : this is a body line" is changed to "Notaheader: this is a body line" (the space between "Notaheader" and the colon is removed). Expected Results: formail should echo exactly what printf gave it, as the Subject/To/From headers are correct, and the "Notaheader" line is in the message body. Additional info: The HISTORY file at www.procmail.org suggests that this problem was introduced in procmail 3.14 and fixed in procmail 3.15. I have tested the formail binary from the official procmail 3.15.1 distribution, and it does seem to handle these messages properly.

procmail-3.15.1-1 which is currently in Rawhide should fix this problem.
