What works for me is the following. Enable guards No fixup protocol SMTP 25 Conduit permit tcp host x.x.x.x eq smtp any
In Imail I have SMTP security set to relay for 127.0.0.1 only and then I use SMTP Auth because all of are agents are on another network that we do not support and I have no way of knowing there IPs. Don't ask the travel industry is verrrry different. Seems to work. ~Paul~ -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of David Sullivan Sent: Monday, May 06, 2002 11:39 AM To: [EMAIL PROTECTED] Subject: [IMail Forum] SMTP Commands Hi, We're installing a Cisco Pix firewall with "MailGuard" feature that is suppose to clean-up and filter SMTP commands. I am trying to verify that limiting SMTP to these commands will not affect our Imail Server. I called Ipswitch tech support and they said it was OK but she didn't sound to sure about her answer. Can anyone here give me some feedback? Here is the description of the feature: "These seven minimum-required commands are: HELO, MAIL, RCPT, DATA, RSET, NOOP, and QUIT. Other commands, such as KILL, WIZ, and so forth, are intercepted by the PIX and they are never sent to the mail server on the inside of your network. The PIX responds with an "OK" to even denied commands, so attackers would not know that their attempts are being thwarted."
