Hi,
It's a patch to cut some code that becomes useless, when you build
your binary with a ./configure option like --without-mail_smtp_module
and so on.
I re-compile the code using all combination of the 3
--without-mail_*_module options to test it.
It is just a first shot, in order to to reduce a bit the amount of
auth-http code .
Any comments are welcome.
Regards,
Filipe da Silva

Mail: add guards around imap, pop3, smtp dedicated source code.
No functionnal change.
Disable some code that becomes unnecessary when adding configure directives
like --without-mail_(smtp|imap|pop3)_module .
