ASA 5520 & smtp

How do I disable port 25? The only thing I can find in the ASDM about SMTP is configuring the servers. I don't want that port open at all.

for inbound access all the ports are implicit deny unless you open any explicitly

I don't mean allowing it through the firewall. I want to disable the smtp logging service so port 25 does not show as open on a port scan of the ASA.

under global policy map , you may enable inspect ESMTP

Re: ASA 5520 & smtp

Here is my dilemma. When I run Harris Stat against the ASA it comes back with 2 open ports that I need to close. 25, 110. I do not have any server addresses configured on the ASA and want to close these ports.

Is this even possible? I can't find any documents to suggest that is and I can't find the commands that would do it either.
