Comcast Email Woes
news : by Tommy - October 2nd 2007, 07:37PM

Well, it's official (in my eyes at least) Comcast sucks. Time Warner Houston recently sold their internet operations (aka RoadRunner) to Comcast. In doing so they migrated user email accounts to a @comcast.net address, rather than the long @houston.rr.com. Cool, it's shorter, easier for newbs to remember, etc.

I migrated my family (me, jenn, parents) over to Comcast a few weeks ago, problem is, there's no easy web interface to manager user accounts. There very well could be some awesome, ground breaking webapp to do just this, but Comcast doesn't make it easy to find - not like RoadRunner used to. So now, everyone's converted over, but I can't set/change my parents' email passwd so they're more or less locked out of their email until they (or I) call Comcast. Ok, fine. I can call sometime, no problem. For me it's no problem migrating over. I just changed the MX redirect on my neodux.com email address and the mail is routed appropriately - for a while. You see, Comcast has this thing called a blacklist. Lots of people are unhappy with Comcast's blacklist. If your mail server isn't AOL, MSN or some other commercial service, chances are you'll get blacklisted. Guess what happened to mail from neodux.com?

I called Comcast and was on the phone with 2 different technicians for about 45 minutes (not including hold time) trying to A) convey to them the problem and B) how it's their problem and not my "internet security settings". I even had one technician tell me repeatedly and in a condescending tone that there is absolutely no blacklist and that my emails are bouncing due to my mail server. (No way buddy, not when the header tells me your mail server is rejecting it!)

Long story short: Neodux email is now hosted on Dreamhost who, despite my problems with them in the past, is 110,000% better at not screwing up stuff for no reason. Thanks Dreamhost!

For what it's worth, if you get blacklisted, you're supposed to forward email that was rejected, as well as the IP of the originating server (why can't they look that up?!) to the following address:
blacklist_comcastnet@cable.comcast.com

Of course, this isn't knowledge that can be found easily on their website either.

Might I recommend Google Apps for your domain. I have been using it for a while now for my 3 domains. I still have my hosting at Dreamhost, but email is hosted on a much more reliable email host, and a simple web interface. Except for a couple small quirks I rather like it.

Your woes are not limited to Comcast, either. Last weekend I was up at Big Bear Lake, CA using a Charter connection. It seems that Charter has broken DNS agreements and started redirecting all traffic that fails to find a DNS entry to its own search page with ads.

This breaks VPN connections rather quickly. Instead of getting a reject when trying to resolve a VPAN LAN host from the Charter DNS and falling over to the VPN connection, the Charter DNS server redirects to their search page. HTTP, POP3, and FTP services are thus useless via VPN.

Changing DNS servers to 4.2.2.2 instead of what Charter hands out with DHCP resolved the issue but it seems to me that if cable companies stopped screwing with things the world would be much better.

I never though I'd say it but after all the stories about Comcast and Charter, I am really enjoying Cox.

Ah yes, good old 4.2.2.2 and her sister 4.2.2.1.

Those two DNS servers have saved the day more than a few times.

Comcast also breaks your torrents by using "Packet Shaping" crap. If they catch you on torrent traffic they keep sending you RST packets so you lose your connection to torrents. Apparently Comcast thinks BitTorrent is evil and doesn't think about the folks that download Linux Distros or the TV shows they missed.

To bypass this garbage, you can use that nifty SSH tunnel, or use a different port.
