Ignore the body_checks advice. What you are looking for is a MIME
content_filter that can drop attachments using content type, file name or
file content (e.g. AV signature) criteria. Postfix does not currently
support internal filtering APIs. Instead it supports forwarding mail to an
SMTP proxy which loops it back into Postfix via a different SMTP
listener which is free to modify the message content in any way
it sees fit. The filter can also be a UNIX command which reads the
message on standard input (actually both use the same underlying
"transport" abstraction via master.cf). The Postfix part of this is
documented in FILTER_README. The rest depends on the filter technology you
choose.
