Actually, NMAP offers a decent method of identification on TWO factors: (1) identify the software running on the target server (if applicable), and (2) identify the version of the software. The parameters are: nmap -A -T4 -F <target hostname or IP address> If the site is blocking ICMP, try it with the "-P0" option.

When you telnet into port 25 on most smtp servers it will tell you what it is even if it is behind a firewall. The firewall will pass the traffic directly into the server. For example if someone has put their domino server out onto the internet, when you telnet into port 25 it will tell you the version of Domino server that is running. Also while most admins will use the generic mail.xxxx.xxx in their DNS records, the smtp server will tell you what it's true name is. This can either give you a clue as to what software the server is running or it can even tell you the naming scheme the company uses. Hope it helps. -----Original Message----- From: Doug Fox [mailto:dfox168 () hotmail com] Sent: Wednesday, February 01, 2006 8:30 AM To: pen-test () securityfocus com Subject: Identify the make and model of a Mail Server One can use NetCraft (www.netcraft.com) to identify a web server if it is Appache, IIS, etc. How can one identify a mail server behind a firewall, be it Exchange, GroupWise, or Lotus Notes? nmap or nessus helps identify if a mail server is available through tcp port 25. Any info is much appreciated!
