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?


Yes. I can confirm. And it appears to be *content filtering*. Anything
with a URL containing appears to be getting the ixnay.
