Roadrunner turns images off by default

Earlier this week DirectMag published an article talking about RoadRunner blocking images by default. I did talk to someone over at RoadRunner and found out a few more details about this change.
What is happening is that RR is rolling out a new web interface. This interface has both a bulk/spam filter and has images disabled by default.
I do not expect sender to notice this change in the open rates of RoadRunner addresses. Most RoadRunner customers use their own mail client (Outlook, Outlook Express, Thunderbird, etc.) and not the RR web interface. The number of uses this change touches is a very small fraction of the RR users.

Changes at RoadRunner

I’ve been hearing rumors that some *.rr.com domains have been bouncing all mail sent to them. Those domains belong to customers that were moved to Comcast as part of the RoadRunner / Comcast / Adelphia purchase and customer swap. As a courtesy, RoadRunner forwarded mail to comcast for those former RoadRunner customers, but have ceased to do so.
Mail to any address in the following *.rr.com domains will no longer be delivered.
jam.rr.com
midsouth.rr.com
mn.rr.com
se.rr.com
sport.rr.com
swfla.rr.com
ucwphilly.rr.com
houston.rr.com
These addresses should be removed from your lists. These users now have Comcast addresses. You cannot just substitute the Comcast domain for the RoadRunner domain as users were required to choose new localparts. That means bobjones@houston.rr.com may not be, and probably is not, bobjones@comcast.
