smtptrapd for fake secondary MX

[Jeff A. Earickson]

Gang,

I am experimenting with the use of smtptrapd
(http://smtptrapd.inodes.org/) on a box that has been
declared as a secondary MX for our domain.  The idea
here is that spambots that gravitate to higher MX servers
go to smtptrapd and get tmpfail rejected, instead of going
to our real primary MX and clogging up our mailer software.
There was an article about this code in a recent issue of
SysAdmin magazine.

I've got it installed and working for our domain, and I'm
watching the syslogging.  And I'm waiting for the phone to
ring with complaints.  Anybody else tried this approach?
