We don't want to kill it.  We want the JVM to dump the thread status, which
is what it will do when receiving that signal.

Yes, but installing them might be a challenge.  Most of them would be shared
in the form of ipfw or iptables scripts by administrators.  It would be a
bit overboard to import the entirety of xbl-sbl.spamhaus.org.  :-)

> What do you mean with "tune the TCP/IP stack"?

See www.redbooks.ibm.com/abstracts/redp3943.html.  That's for MS-Windows,
but it really doesn't have much to say compared to the options available and
described in the same book for *nix, e.g.,
www.redbooks.ibm.com/redpapers/pdfs/redp3861.pdf.

> How can I "fast fail" the connections?

One way would be to enable DNSRBL support in the SMTP handler chain.
