Some general notes on a bounce killer are in release notes,
search for 'bounce killer'.

Bounce killer tries to recognize some forms of bounce messages,
but is rather conservative about it. At the end of a bounce test,
if a bounce killer did not recognize a message as a bounce, but
a message is exhibiting some indication that it might have been
some form of an auto-response, then you see this informative
message logged at log level 2. Currently these indications
are: auto-response, From or return-path is a 'postmaster',
or a SpamAssassin rule ANY_BOUNCE_MESSAGE was hit.

So nothing to worry about. This is mostly an information
for program development that perhaps a bounce killer may
be missing recognition of some unusual form of a bounce.
