James, Are you sending from inside or outside your firewall? If you can do what you mentioned (steps 1-4) and you're able to send to anyone from outside your firewall please re-read sendmail.org, you are STILL an open relay. -Walden ------------ Walden H Leverich III President Tech Software (516)627-3800 x11 WaldenL@TechSoftInc.com http://www.TechSoftInc.com -----Original Message----- From: James Rich [mailto:james@eaerich.com] Sent: Wednesday, November 21, 2001 2:29 PM To: 'midrange-l@midrange.com' Subject: RE: fix.your.open.relay.or.die.net On Wed, 21 Nov 2001, Walden H.

Yes, I know that. I thought Brad was referring to getting mail with a client (i.e. reading his mail). Usually "get" is not used when referring to SMTP since SMTP server do not initiate anything to get mail, they only get mail when someone sends it to them. SMTP servers really only send, never get. By special firewall rules I meant things like port forwarding, timed waits, etc. The firewall is just a stateful firewall with pretty standard rules in it. Don't want to say too much more about it, though... Fixing SMTP servers to not be open relays *and* allow clients to send email from anywhere on the net is easy. I believe most aren't sure of how their SMTP services should be done, and enabling open relaying is easy and fixes the problem. Of course I may be somewhat naive about what some people's SMTP needs are. But for most this should work: 1. Close your open relay (see sendmail.org or read the bat book for info on what an open relay is, how to close it, and to correctly route email). 2. Stick your email address into netscape 3. Stick your SMTP server into netscape 4. Send email Works every time.
