Use the command "no fixup smtp" Maybe it was disabled before the ver. upgrade?
The fixup protocol for SMTP on a PIX has a tendency to mudge any mail sessions that use ESTMP. In other words, it limits the number of commands used in an SMTP session. Some Email servers (e.g. Exchange 5.5 and 2000) use ESMTP and balk when it is disabled. -----Original Message----- From: george gittins [mailto:[EMAIL PROTECTED]] Sent: Wednesday, March 27, 2002 11:16 AM To: [EMAIL PROTECTED] Subject: pix and e-mail problem [7:39643] For the past months i been receiving multiple e-mails from the outside world.
