In switching website hosts, I had to switch mailing list providers as well. To receive these weblog posts via e-mail, send a blank e-mail message to weblog-subscribe@eugenewei.com. And to unsubscribe, yes, just send a message to weblog-unsubscribe@eugenewei.com. The old mailing list no longer works so current subscribers should do this to continue receiving posts via e-mail.
The other option is to syndicate this blog via its RSS 1.0 feed and pull it into your newsreader. Or you can just read it here as a web page, though that's so 1999.
