What would be the best method for (temporarily) blocking all mail from a particular (internal) IP? Or alternatively, blocking all mail with a particular "MAIL FROM" address?
For instance, blocking all mail from 1.2.3.4, or alternatively, from bro...@badhost.example.com<mailto:bro...@badhost.example.com>. The purpose would be if some departmental server has a runaway process that is spewing out error messages on the weekend and there is a delay in contacting the sysadmin to shut it down.
