I've been looking around to see how I can deal with a particular site that doesn't report a FQDN in the HELO/EHLO line. I have smtpd_recipient_restrictions containing:
reject_non_fqdn_sender reject_non_fqdn_recipient reject_non_fqdn_hostname to help with SPAM issues. I want these enforced for everyone EXCEPT one site (heck, one IP) that needs to talk to me (but I've been unable to get their admin to fix their broken configuration). Is this possible or am I just missing something really obvious? Any pointers would be greatly appreciated. Thanks! -Michael
