The option is interesting, do you have an example?
I tried to use it but it didn’t work for me.
smtpd_recipient_restrictions =
check_recipient_mx_access cidr:/etc/postfix/recipient_mx_access.cidr
52.164.206.56 reject

Any chance of blocking the MX of a recipient? Reading the
documentation I
found the parameter "check_sender_mx_access" but I think it refers to a
sender and not a recipient.
there's also check_recipient_mx_access, I use few of them for this
kind of abusers.
