Or block tke mail to any recipient starting with "|"
In postfix that could be done with

check_recipient_access regexp:/etc/postfix/blocked_recipients

with /etc/postfix/blocked_recipients:

/^\|/    REJECT

I would weed that absolutely unwanted stuff out at the MTA level to
keep resource usage low (bandwidth, mostly)

I'v seen sendmail & postfix log the non-existing addresses.
