The EHLO verb and SMTP extensions - http://cr.yp.to/smtp/ehlo.html
EHLO is just like HELO except that the server's response text provides computer-readable information about the server's abilities. Here is what happens if the server accepts EHLO (required code 250). On the first response line, the text begins with the server's name. On each response line past the first, the text is an extension, followed optionally by a space and an argument, followed optionally by a space and another argument, etc. The extension is a nonempty string of letters, digits, and hyphens. Each argument is a nonempty string of graphical ASCII characters. -----Original Message----- From: Robert Williams [mailto:[EMAIL PROTECTED]] Sent: Monday, October 07, 2002 1:10 PM To: Exchange Discussions Subject: Stupid newbie question-what is "EHLO"? I am getting the following errors in my firewall logs? smtp[3041]: 334 Warning: Denied access to command 'EHLO logonlvm01.logonlv.com' from [66.93.249.102] What does this mean? And it is a problem with my firewall? Or the way I have my exchange setup? Thank You, Robert Williams Senior Network Administrator Raypak, Inc.
