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. -- Viktor.
