If he were to put all the mail addresses into a TO or CC field (and given what he is planning, he may be stupid enough to do this), and one of the recipients is on an unpatched Microsoft Small Business Server 2003, then he may produce a torrent of regenerated emails.

The link above doesn't really explain the outcome of hitting this fault very well, but it is "interesting". The unpatched server regenerates the mail to all recipients again, repeatedly, about once a minute, until it is switched off or patched. And every single email appears to come from the original sender.

Cue lots of very very irate people telling you to stop spamming them - and there is nothing you can do directly other than identify the sender from the mail headers and try and persuade them it is their system at fault.
I have seen this happen a couple of times to our customers, it isn't pretty.
So, from a business perspective, this act could destroy customer relations rather than create them. Is that good enough.
