The manpage you quote dates from procmail 3.06 or so. 3.10 and later
have correctly paranoid manpages.

Solution: change that last subject to read:

* ^Subject:.*request [0-9a-z]

and add the condition:

* ! ^Subject:.*[/.]\.

That will protect you from ".."s and keep dot files in general from
being fetched. Totally ripping out the entire recipe and inserting
the version from the version 3.11pre* manpage would probably be a
good idea, assuming you have at least 3.10.

(Note: procmail regexps are case insensitive by default)
