If I configure my locally hosted SMTP server to only accept SMTPS connections (secure SMTP port 465/587), how much mail will I lose because sender(s) don't support sending on SMTPS?
Are the major mail providers fully complaint of SMTPS on 587?
My web server (apache2) is continually pounded by malicious bots, asking for URLs like these:

I'd like a nightly cron process to find any host requesting a "malicious" URL, and add them to an HTTP equivalent to hosts.deny.
I would imagine that there would be a set of regexps defining malicious URLs, and well as possibly some apache plugin to easily do the host denying (without having to do an httpd restart every night).
Does anything like this exist?
