+The bug ID is CSCds90792. The "fixup protocol smtp" feature does

+How does one recognize a mailer behind a Cisco PIX with "fixup

+protocol smtp command changes the characters in the SMTP banner to
+asterisks except for the "2", "0", "0" and space characters.

+When you connect to a mailer behind such a filter you see something
