But using my ISP SMTP server as a magic-relay would require it to relay 3rd party messages to 3rd party servers. I assume no ISP would allow this behavior, because if they would, there are BOTS around the net looking for this kind of servers, and blacklist them (spammers love those). http://rbls.org and http://openrbl.org are examples for those things. ================================================================To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
