A setting like that would likely be at exim (or similar). Most smtp servers
allow some sort of wildcards, as those are used to pass or not e-mails to
list servers and/or handle custom mail forward rules.

At client level, one could use dovecot with pigeonhole to have sieve
rules to filter e-mails. That's what I do here.

Yeah, agreed: those are very rare exceptions. I remember just one or 
two cases where a media fix patch couldn't be queued to stable. 
The already-existing workflow worked for those.

From my side, I'm fine with whatever-explicit-long-filter-email.
