I don't know that ISP, but it is possible for them to use your IP address for authentication. To get the right IP address, you have to use their server for dialin, of course. Another common scheme is smtp-after-pop. Here, the idea is that you connect to the POP server, and if that's successful, then for 5 minutes (or whatever) you're (your IP address is) allowed to use the SMTP server. I think there are also schemes for doing authentication within SMTP, but I think they are rarely used. They are also non-standard, I think. kai -- A large number of young women don't trust men with beards. (BFBS Radio)
