The fault here is no Apple's. It is a sin to parse MIME with regexps.
A proper MIME parser is required to do the job right.
The Postfix header checks are a not a complete solution, just a cheap
filter that can stop the most common junk. It is a bug in the (sample)
filter that it admits false positives. Any regexp filter will inevitably
have false negatives.
