Use milter-regex. <https://linux.die.net/man/8/milter-regex> Very
flexible. Chances are you want to keep these guys out of more than your
request address but milter-regex could be fine tuned for one specific
address or pattern of addresses. Like:
|# filter requests from GMAIL
reject "Your requests offend me."||
||envrcpt /-request at lists.ziobro.info/||
The offending message will never even get on your machine. In general
you want to filter in the SMTP stream before an undesireable message
gets on to your machine. Once a message gets put into Mailman there is
the potential of backscatter.
