Comments? My updated reply from Feb 8, 2005: The IIS 4.0, 5.0, and 6.0 SMTP service is a very simple Windows based MTA. If all you need is a simple MTA, then obviously it will do the job for you. What is a simple Windows MTA? In my opinion, it's one that is: -Primarily configured through a GUI in Windows with check boxes and radio buttons -Has a limited configuration in comparison to Postfix, Sendmail, qmail, Exim, etc. -Has limited customization " " -Is pretty much RFC compliant -Limited content and connection filtering In other words, it was designed as an MTA, and it does just that. Personally, the IIS 6.0 SMTP service is great for internal SMTP communication, however, I prefer to have Postfix as my Internet facing SMTP MTA server/firewall/gateway. With this configuration, not only do I not have to be consumed with security patches on my Internet accessible services, but I also have an almost infinite level of configuration options. ...D
