You will have to contact the appears comcast is blocking may need to contact comcast...either the client has some spam filters blocking you or their ISP has some spam filters blocking will have to get on the phone to get this resolved.

Check this out:

That IP address is on a Spam block list, because it is cable modem connection.  Almost nobody runs their own mail server from a cable connection, and as such, 99% of e-mail coming from an address like that is going to be spam.

It isn't the .fr domain that's blocking your connection.  It's the mail server at the MX record for that is blocking you.  This is because the server uses a block list to look up the IP of the person connecting, and if it's on the list, it doesn't accept the message.  However, I'm sure there are lots of servers on the Internet using the same block list, and so none of those will accept your e-mail either.

The link above contains instructions on how to get your address removed from the block list, but I don't think you're going to be successful because 99% of incoming mail from a cable modem address really is Spam.  You'll see that it isn't your specific address that's blocked, but a whole range of them.

ComCast is talking about blocking mail from their mail server.  I'm pretty sure they don't do any blocking at all when it comes to people running their own mail server.

You can contact, but I doubt you'll convince them to stop using the block list.  Those things are necessary to fight the onslaught of spam, even if it hurts some other innocent users.  So, that leaves getting your IP off the block list, and like I said before, I don't think they'll do it for you.

Your other option is to see if you can have your mail server relay the message to ComCast's mail server, and have it deliver it.  I doubt it's IP is blocked.  However, I'm not sure they'll accept relayed messages.

Here is a page that tells why they have IP ranges belonging to cable modem users in their block list:

It isn't you, it's just about every cable modem user out there.  It just checked and mine is listed too.
