Comcast discarding email with shortened URLs?

I just got a report that comcast is simply discarding all email containing URLs shortened with our easyURL shortening service (easyURL[dot]net). No bounce, no refusal to accept, just accepting and then discarding. Anybody else confirm this with other URL shortening services or are we just the lucky ones? Is there a comcast postmaster on list we can talk to about this? -mark -- Mark Jeftovic <markjr@easydns.com> Founder / President, easyDNS Technologies Inc.
