I never said I rejected based on the HELO, I reject based on the client hostname ;-), the hello I just check that it is formatted properly. > >> The hostmaster for sparkplug.kernel-panic.org needs to ask the IP >> address provider to add the PTR record ( it should point back to >> "sparkplug.kernel-panic.org" ). > > I disagree. The RFC disagrees. The IP of one or more of your mail server(s) have no reverse DNS (PTR) entries. RFC1912 2.1 says you should have a reverse DNS for all your mail servers. It is strongly urged that you have them, as many mailservers will not accept mail from mailservers with no reverse DNS entry. MX records are: 161.246.98.63.in-addr.arpa [No reverse DNS entry (rcode: 3 ancount: 0)] -- Guillermo Antonio Amaral Bastidas (gamaral) Free/Libre/Open-Source Software Advocate & KDE Developer http://blog.guillermoamaral.com/ -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
