Eli Barzilay 2410b71326 Revise `net/sendmail'. ... * Move the `X-Mailer' header to the top, so that the interesting headers are all together at the bottom (the top gets littered by server headers anyway). * Use `subprocess' directly (`process*' wasn't really doing anything more than that). * Allow the sender to be `#f', leaving the header out. This makes all sendmails that I've used use the username that is running the process. * Just search for a sendmail program: don't barf on windows, so it can be used in case there is a sendmail.exe executable there. * Remove `no-mail-recipients' to make it in-line with other racket code that doesn't raise super-specific exceptions. * Use port counting instead of doing the counts manually, much simpler code. original commit: f9d07d84009e69a0202390fd828c00d330c19611		2011-12-20 15:53:40 -05:00
