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
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
* close the port on the firewall for the source IP
* check_sender_access
