The problem isn't about names at all, it is about file TYPE;-).
Run the file command on the offending file and see _why_ it gets
labled as an executable... Permanent solutions might lie in the
direction of getting your file command patched, interrim solutions
might be editing your magic file so that the file command detects it
as the correct thing, or at least not as an executable.

Or you could make an exception for the sender/recipient combo in
MailScanner ... requires a ruleset on the filtetype rules setting and
an "overload" file as described in the wiki
(http://wiki.mailscanner.info/doku.php?id=documentation:configuration:rulesets:overloading)
... just remember to do something appropriate for the _filetype_
rules, not filenames;-).
