XTND XMIT Xplanation -- Several readers reminded us of a solution to a problem Glenn mentioned in his anti-spam article in NetBITS-004. If an ISP prevents relaying to protect its servers against being exploited by spammers, that action also prevents legitimate users from sending mail when not dialed into the ISP's own networks. This might happen, for instance, if an EarthLink user wanted to send mail from his EarthLink account while connected to the Internet via a dedicated connection at work. One solution to this problem is the XTND XMIT extension to POP (Post Office Protocol, which is generally used only for receiving mail). If both your mail server and your email program support XTND XMIT, you can send email via POP as well as receive it. Since POP is authenticated, XTND XMIT works for sending mail no matter how you connect to the mail server in question. Contact the support folks at your ISP if you think you might want to use XTND XMIT. They should be able to tell you if their mail server supports XTND XMIT, and they may know how to turn it on in your email program (it's a somewhat hidden setting in Eudora for both Macintosh and Windows, though I don't know about other email programs).
