Hello list, I have a strange problem, when I send a mail to a mail address with an "!" in the localpart, I got a "relay access denied", but the character is allowed in the RFC:
Jul 3 09:46:28 mta postfix/smtpd[6229]: NOQUEUE: reject: RCPT from fmmailgate03.web.de[217.72.192.234]: 554 5.7.1 <abc!d...@abc.de>: Relay access denied; from=<a...@web.de> to=<abc!d...@abc.de> proto=ESMTP helo=<fmmailgate03.web.de> Jul 3 09:46:28 mta postfix/smtpd[6229]: disconnect from fmmailgate03.web.de[217.72.192.234] The server is a spamfilter only forwarding to internal servers and other special characters like "|" work fine. Does the exclamation mark have a special meaning? If there is a problem with the character I would expect something like "Bad recipient address syntax". Is there anything I could do to receive these mails? Thank you, Daniel
