CHAPTER 5. EXAMPLES OF SCHEME SERVLETS

5.6

Automated Email

Our final example of basic servlets demonstrates how to write a servlet that

sends email. Again, here we assume that the library  mail.scm  has been

preloaded. The code for this library is in the appendix. This library defines

the send mail procedure which is called as follows:

(send mail request TO FROM SUBJECT TEXT)

Here TO, FROM, SUBJECT, and TEXT are strings.

For example, to send mail to to someone@xxyyzz.com from  from me@myserver.com 

you would write

(send mail

request

"to someone@xxyyzz.com"

"from me@myserver.com"

"This is a test"

{ Cool, this really works and I can include

scheme expressions like this:

[(* 111 111)] is 111 squared! })

The  to  and  from  email addresses can come from the servlet parameters (for

sending confirmation email for example). You should avoid using  fake  return

addresses as this is annoying and the email can often be easily traced back to

you anyway!
