mailR: Generate mails and send them via sendmail
You can use this package to generate the console commands to send mail with the sendmail command line tool. Digital encryption via OpenPGP is also supported, signatures don't work yet. You need a working setup of the required tools, namely postfix/sendmail, qprint and GnuPG, for this package to be really useful. It was originally inspired by the need of the C3S project (https://C3S.cc) for a mail interface to R. Note that mailR is in its early stages and most likely not ready for professional use!
