Hi all. I'm installing a new SMTP gateway for my company. I'm using an IIS 6.0 SMTP server on a Windows 2003 Server std machine to route all incoming/outcoming mail to/from my Exchange Server.

Now all it's working fine but I don't know if it is a good idea follow the steps to remove the SMTP server banner. Of course it can help in case someone is planning to attack the server, but i think that the version banner is used for some operations that won't work if I remove it, right?

The question is, would you remove the banner in my case?

Thank you!
