That is correct for the <> case. But TMDA recognizes "xyz <@yahoo.com>" for the envelope sender as <> - and that is the problem! > Your LOGFILE_INCOMING file will show you exactly which rule allowed the > message through. And the information in this file is the following: | Date: Fri Aug 8 18:27:08 CEST 2003 | Sndr: <> | From: "" <@prihost.com> | To: [EMAIL PROTECTED] | Subj: Can you reduce your mortgage payment? Find out now. | Actn: OK (from <> ok) (2661) As you see the rule "from <> ok" is applied. But the envelope sender IS NOT <> but '"" <@prihost.com>' like in the From line. I've tested that out and it's always the same result: the message is coming through with "from <> ok"! > > > Does anybody know how to stop at least the messages with an envelope > > sender starting with @? > > Postfix has a configuration option called 'strict_rfc821_envelopes' > that you can enable, which will block mailformed messages like this. > > You should apply the equivalent fix to whatever MTA you are running.

But wouldn't that block all messages from yahoo.com ([EMAIL PROTECTED], [EMAIL PROTECTED], and so on)? But I want to block only ONE address: [EMAIL PROTECTED] - so I have to use a kind of escape character to prevent the system from interpreting the * as a wildcard -- is one available?
