Hello,
There is a bug in Postfix's 'smtpd_helo_required' option, with the
attribute 'reject_non_fqdn_helo_hostname'.
Postfix does not accept an address literal for a HELO or EHLO message,
and Postfix's documentation says a FQDN is required for a HELO or EHLO.
This is not RFC 2821 states under '4.1.1.1 Extended HELLO (EHLO) or
HELLO (HELO)' that an address literal must be accepted.
Postfix documentation will also need to be updated with the correct
information:
http://www.postfix.org/postconf.5.html#smtpd_helo_restrictions
Also, my e-mail address was recently removed from the postfix-devel when
I did not request it, nor was I consulted over the decision. If this
happens again then I will cease contributing to Postfix.
Regards,
Nikolas Kallis
