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.

eh, not this kind, unless you want to block anything with MX/A pointing to 104.215.95.187 and 54.159.98.68.

for hotmaul.com and hormail.com use simple check_sender_access and check_recipient_access.
