The settings you want to look at are smtp_banner and helo_data. If I remember correctly, helo_data defaults to $primary_hostname and smtp_banner defaults to something with $primary_host_name and exim's version number. In my configuration, I just have primary_hostname to my hostname (e.g. primay_hostname = dune.jamesr.biz) which also sets the smtp banner displayed when connecting to remote hosts. My relavent debconf configs are internet site, number of dns-queries minimal to no. I am thinking the primary_hostname gets set in the config file by doing a reverse lookup on the ip of my server. Does a lookup of the ip of the interface you are sending mail resolve to the name of your firewall? -- James Richardson Debian GNU/Linux Consultant http://www.linkedin.com/in/jamesrichardsonconsulting
