>From: Mark A. Manske [mailto:mmanske@minter-weisman.com] >why can someone telnet to your mail service? You can't stop it[1]. Try "telnet <smtpserver> 25" from a command prompt on a pc. The 25 identifies the port number to connect to on the remote machine, port 25 is the mail port. If you restricted someone from telnetting to port 25 you'd also restrict another mail server from connecting. -Walden [1]There is a half-baked thing you can do that says if the data coming in is being sent one byte at a time then disconnect since most servers send chunks of data but telnet sends byte at a time. Of course telnet can be changed to send line at a time so that wouldn't help too much. ------------ Walden H Leverich III President Tech Software (516) 627-3800 x11 (208) 692-3308 eFax WaldenL@TechSoftInc.com http://www.TechSoftInc.com Quiquid latine dictum sit altum viditur.
