it may not be a hole, comcast is known for filtering what they don't like:

from nbc news:

"Comcast's approach to traffic shaping is different because of the
drastic effect it has on one type of traffic     in some cases blocking
it rather than slowing it down     and the method used, which is
difficult to circumvent and involves the company falsifying network
traffic"

"They're using sophisticated technology to degrade service, which
probably costs them a lot of money. It would be better to see them use
that money to improve service"

That would be cool. Bouncing mail, that's becouse Comcast don;t tell
you they do not provide connectivity to the whole Internet..   And my
mail sever is on the part they don't offer you.

Last time I checked, it was like this, if someone has an absolutely
imperatively important need to run their own mailserver, (mail going
in both directions), they needed to make a specific request. And then
convince or confuse the offended ISP.

    I do have that need, and I do run a mail server, and I've made no
such request.   I'm on a Business class connection, which shares neither
bandwidth, nor netblocks with dynamics, nor support staff.   (my netblock
*used* to be dynamic, but hasn't been used that way for several years)

    For example, the last time I called them, the *first person who
answered the phone* logged into a nameserver and corrected a PTR record
for me. (I checked!)

    Now, the routing issue Peter mentioned...that's a different matter,
which I will need to check out.   Lots of people and a few companies use
my network, and I've not had any issues thus far.   I've always despised
the "cable company" ISPs, for obvious reasons, but Comcast Business has
surprised me by being absolutely top-notch from (my) day one.

They just have no connectivity. That's why you have no DECnet tunnel
to Stockholm. You should ask them for a discount and use that money to
buy services from someone else to fill the Comcast connectivity wholes.
