How to send e-mail from Silverlight without ASP.NET server?

My task is simple, send an e-mail f开发者_StackOverflow社区rom a Silverlight app, but it has to work in most webservers so, Linux, Apache. Cannot use Windows Servers.

Is my best bet to create a simple PHP script to do the heavy lifting and make request to that using SL?

Even with a ASP.NET you would need to write code server side to accept a request from SL to send an email. Ok so Visual Studio would make creating that much easier but essentially either with PHP, ASP, ASP.NET or whatever you need a service to for SL to send its request to send an email.

I know very little about Apache but PHP would be one way to do it, although I'm sure there would be other ways to create a web service that SL could consume.
