I know this should be easy but...I don't get into routers very often. I have a Cisco ASA 5505. I am having an issue receiving some emails. I was told that the email is failing at the router and that I need to disable SMTP Fix-up or ESMTP discovery. The only thing I find in the router config is inspect esmpt. When I type in "no inspect esmp"t I get an error:
ERROR: Invalid input detected at ' ^ ' marker.
Your help would be appreciated.
