Python's smtplib module can do that (well, you'll have to look up the
MX record by your own, but it should be simple to write a shell
wrapper that can do that and then call the bot with appropriate
arguments).  You can use the .putcmd() and .getreply() methods to
check the RCPT TO, and the .sendmail() methods to submit a report.
