Steve, If you don't have a valid ptr record those servers tend to delay your mail as they think you might be a spammer.
Visit http://www.mxtoolbox.com and type in your domain. It will be one of the tests that is run. If you don't have a ptr. Contact you ISP about this. If they give you some bull about it being your responsibility ask to talk to the NOC and someone who knows what a ptr is.
