issues with smtp

Hi all. My users are connected to the internet via cisco asa 5510. When any of my user try to do a telnet to a public mail server on port 25, the response would be 220 ********. It shows asterix instead of proper wordings. However if we use a different firewall, we would not have such a problem. I have enabled inspection of esmtp but to no avail. Pls adivse. Thks in advance.

Re: issues with smtp

I think you want to disable the 'inspect esmtp', not enable it, to stop this behavior.

Re: issues with smtp

a better question is why are your users telneting to port 25 on external servers and why do they need to see the SMTP information like that?
