"Windows Server 2003, Web Edition, can be used solely to deploy Web pages, Web sites, Web applications, and Web services. If your application is to be used is to be used under these circumstances there is no problem with you using Windows Server 2003, Web Edition."
Unless someone has something different I'm going with what they told me.
I haven't looked at the SPLA (Service Provider) EULA but... http://www.microsoft.com/windowsserver2003/evaluation/overview/web.mspx
When they say 'web-application' that could really mean web only i.e. port 80, and not a mail application like Imail.
Given the web edition comes with a new bundled Microsoft POP mail server that does seem crazy though.
