Postfix (which I know Dahwal uses) is very well capable of rejecting
due to any pattern on headers or body. Usually rejections will be
effected at RCPT TO: or after DATA (in compliance with the RFCs).
Why rejections due to DATA content (header or body) wouldn't be
possible in any particular MTA... Well, it is more a limitation in
that MTA than anything else;-).
And no, I'm not looking for an MTA war:-)
