local_host_blacklist should support ! constructs, so

!146.232.48.3
!146.232.48.2
!146.232.49.2
<convenience snip>
!146.232.197.237
146.232.196.0/23

Should just work.

If not, a possible hook would be via CHECK_RCPT_LOCAL_ACL_FILE.

It takes some practice and experience, yes. But the learning curve is
not that steep.
