The scenario assumes that the server has advertised "CHANNEL=mailto" 
in the capabilities.

Why would this request be absurd?

Um, this is just nonsense. Of course when you send the data to RTSP, 
for example, you're going to send all of the appropriate RTSP 
commands and then you send the data down the pipe. If it helps, make 
believe that you are channeling the message to a process that handles 
the mailto, and that process is the one that prepends Resent-* 
fields. Remember, what comes after the Resent-* fields is the 
original data, completely unmodified.

What data content is being modified here? You are simply sending the 
data (unchanged) to another process which is going to do something 
with it. In some cases, that will be "Play the sounds to the user 
using a speaker". In my case, it will be "Send this data via SMTP". 
What's the problem?
