Re: message did not reach some or all



I have suddenly received many of those randomly lately also. I attribute
it to DNS errors possibly related to the DNS vulnerability from last month.

When I enter the domain on DNS Stuff I get this warning

WARNING: One or more of your mailservers is claiming to be a host other
than
what it really is (the SMTP greeting should be a 3-digit code, followed by
a
space or a dash, then the host name). If your mailserver sends out E-mail
using this domain in its EHLO or HELO, your E-mail might get blocked by
anti-spam software. This is also a technical violation of RFC821 4.3 (and
RFC2821 4.3.1). Note that the hostname given in the SMTP greeting should
have
an A record pointing back to the same server. Note that this one test may
use
a cached DNS record.

I can send and receive from the domain.
