Does your SMTP server not do authentication? That would certain get the 
auditors' attention.

Do your users respond to phish attempts? Another security problem, and one that 
has nothing to do with the mainframe.

I suppose it's to much to expect for users to look at the trace fields to 
determine the provenances of messages.

Subject: Re: Seeking a tool to do a network security scan of z/OS

Do you mean outside of the mainframe? Not as a single package, but NMAP
will show you which ports are opened on the mainframe. If your mainframe
answers the scan, you already have a problem... Now assume that port 25 is
open and your mail server is configured an MTA. One can connect to the
server with HELLO call and send emails under fake name and domain as spam
to collect userids, passwords and other secrets.

It's a good idea to have an extra agent to IronSphere to do that -)
