Any suggestions how to get around/deal with comcast blocking port 25

post #1 of 9
Thread Starter 
so I was setting up my exchange 2010 server only to run into the fact that Comcast blocks the default smtp port. I can easily enough change my outgoing ports but how do I deal with incoming mail if that port is blocked on the ISP level? Is there any record I could install into my domain host that would in effect route any traffic on port 25 to a different port?

You should be able to call them and have them unblock it. Or have the exchange server run off an open port. I have had to do that years ago with qwest, I cant even remember what it was for it was so long ago. Its not like you would be asking them to allow you to open the ports to download pirated movies or something, threaten them with change of service due to incompatibility they will listen.

They blocked that port ages ago because of some worm/virus. They most likely won't unblock it because even running a mailserver is against their TOS, so how do you even ask?

That strategy rarely works anymore. Still worth a try I guess but I wouldn't hold my breath.

Really? Didn't know they had such strict TOS. Might have to switch to a comcast business account or something to be able to convince them. Its worth one argument atleast though. Worse they could say is no tongue.gif
