With the smtp fixup applied. Users who access the email server via their ISP connection can not send mail to people with outside email addresses. I guess the command like mail to: gets sent to the email server as a xxxx command by PIX since it is not allowing a telnet session thus a relay message is sent to the user. 5.7.1 can not relay. Once smtp fixup is removed everything is fine.

Exactly what is the behavior that you are trying to alleviate? Depending on the version[1] either Cisco has patched it, or you need a firm commitment from your management that a: you either do not want to use ESMTP and Mailguard stays, even though it doesn't really do anything; or b: you want to use ESMTP and there are no documented or theoretical vulnerabilities that Mailguard cures anyway, and so it should be disabled.[3] Pix guy: "I want mailguard! Waaaahhh!" Exchange guy: "I want it disabled! Waaahhhh!" Pix guy: "Doody-head!" Exchange guy: "Dum-dum face!" -tom [1] more specific than 5.something, please. [2] appropriately patched, as anything in production should be. [3] Garcon, please have that sentence taken out back and shot. > -----Original Message----- > From: Tony Hlabse [mailto:[EMAIL PROTECTED]] > Posted At: Friday, February 22, 2002 11:51 AM > Posted To: MSExchange Mailing List > Conversation: PIX fixup and E2K > Subject: PIX fixup and E2K > > > I have a customers that whats fixup applied to SMTP.
