So... How come I was able to connect via Compuserve and get my Earthlink email with my work laptop while I was just in Houston? -----Original Message----- This was excellent news, until I read on Macfixit today that recently Earthlink had turned off support for the POP XTND XMIT feature. Maybe it's time for me to move to another ISP. :-( Someone wrote: >>It'll let me receive email, but not send unless I'm logged on to one of >>their dial-up POPs. > >Sounds like "POP authenticated SMTP", which isn't quite the same >thing as SMTP auth. The former has one's POP server talking to a >corresponding SMTP server on the same network and saying "yup, >they're online right now".
