Hey all, I work for Earthlink/MindSpring doing broadband tech support, so I thought I'd clear this up :) The POP servers are open, which basically means you can check your mail from whatever connection you have be it AOL, Compuserve, AT&T, take your pick. It should work as long as the service you're using supports it. However, due to many spam and "open relay" problems, the engineers were forced to block port 25 so that only people signed onto the Earthlink network could access our SMTP servers. What this means is that you can't be connected to any other service and send mail through the Earthlink servers (or send mail to another SMTP server from the Earthlink network). However, they do provide a web-based service at www.springmail.com for MindSpringers or http://webmail.earthlink.net for Earthlinkers that can send and receive e-mail and should work from any connection as well. Hope this helps!
