If I'm reading the source code correctly, these are logged to the main
log unconditionally and there is no log selector that controls them. It
might be worth submitting a bug report/RFE to get this changed in the
future, although of course it doesn't help you today.
(This happens in src/src/smtp_in.c, where log_write() is passed a
0 as its first argument and the logging is not conditional on any
checks, just that these events happened.)
