Aside from the fact that it would seem you are condemning your own Imail
installation, there is a more practical problem here: there are a large
number of mail servers (Imail, possibly some others) that report different
domain names during the HELO for the same IP. It is simply not practical to
expect all of these people to upgrade, no matter how desirable it might be.
So even if we all agreed with Comcast in philosophy, there implementation is
arrogant and short-sighted.
Why would it be so hard for them to use this as a weighted test? That way,
a properly configured Imail serve would fail this one test but not be
blacklisted. A spammer would also fail other tests, and would get
blacklisted.

Subject: Re: [IMail Forum] Comcast "Liar Rule" SMTP HELO
Maybe it's just me but ALL the IP's that use different HELO's are spam or
zombies. I use a threshold of 5 different HELO's froma single IP address
and I tag it as a spammer IP. Haven't hit a legitimate on yet. I'm on a
smaller server with less than 10 domains and I have over 100 currently
blacklisted for this.
