fail2ban for spamtraps

[Phil Howard]

I saw fail2ban discussed in another thread.  I was wondering if anyone
here have used it to block based on spamtraps.  I want to set up a
number of dummy users and splatter their email addresses where
spammers would get at them (e.g. white on white text on web pages,
etc).  Then ban the IPs that try to send to N or more of those
addresses, where N is relatively low, like 2.
