You would still have a PTR though so you shouldn't be classified as
improperly configured if you have one. I think the Comcast issue is
really about the HELO response from an Imail server not the PTR.

configured with multiple domain names on a single IP, IMail reports
each domain name in the SMTP handoff (e.g., "mail.mydomain.com").
This actually makes sense to me, but I'm not an expert, so is it
really a violation of the RFCs? Or is it Comcast just being
heavy-handed?
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.
