good day my lord,Hi, I've seen a growing number of bounced mails from Cyrus LMTP where Postfix logs "501 5.5.4 Syntax error in parameters (in reply to MAIL FROM command))" The problem is that those messages really have invalid from adresses, like "RosaSánchez@xxxxxxxxxxxxx", but Postfix still accepts them. Later, Cyrus runs parseaddr() on it ans correctly refuses to accept the mail. Now, I'm interested to hear how others handle this case, if possible how they handle it with postfix. I know that enabling strict_rfc821_envelopes would possibly help but that seem to be a bad idea.
i have also seen this lately -- coming from LMTP as well -- running your 2.3.16 rpm ...
is this related?
thanks
