Now send-mail-function can be one of mailclient-send-it, 
smtpmail-send-it, etc.

One way to keep the ability to change the defaults is to introduce 
special promptonce-send-it as another possible value for 
send-mail-function. It would prompt user for configuration once and 
store actual mail-sending function in separate customizable variable, 
i.e. promptonce-send-mail-function. This promptonce-send-it should be 
made the default value for send-mail-function. This way, users' .emacs 
will have customized promptonce-send-mail-function, but not 
send-mail-function.

Not sure it's worth the complication though, just my 2 cents.
