Just to get past all the noise, here is what I think you're trying to do. Please correct me if I'm wrong:
You have your PC connected to the Internet via Comcast. You want to sent e-mail using your Earthlink's SMTP provider. If this is true, Comcast support won't be able to help you. You need to talk to Earthlink support and tell them that you are away from your normal connection source, and are forced (temporarily) to use Comcast and that you want to be able to send e-mail via Earthlink's SMTP server using your Earthlink account. If they support this, they should be able to give you connection information which you can use in SeaMonkey (or any other client for that matter). Don't get hung up on which client - just have them tell you want needs to be set and someone here can help you translate that into SeaMonkey controls (if necessary). Note that Earthlink is not going to just let any Comcast customer (that is what you are, if only temporarily) connect to their SMTP server and send e-mail. This is what spammers do. They are going to require that you have your client (SeaMonkey) set up to properly authenticate with their system first. I hope this clears things up a bit.
