Since I loaded Enterprise Edition 6.60 we have been getting the following errors when sending to e-mail users on comcast.net.

It looks like it may be related to the new advanced webmail enhancements. We are noticing a larger size to all e-mails as well due to the markup language being inserted using the Microsoft Word editor. I am thinking of going back to version 6.54 for the time being to alleviate the issue. Do you have any ideas on settings to possibly help to correct the issue?
