There is one misconfigured server with DNS MX record which points to IP

so i cannot send any email

all relevant MX records point to non-existent hosts or (invalidly) to IP
addresses

I've got

allow_mx_to_ip set = false

and i dont want to change that


Is there any solution to send email from my local domains to that
misconfigured IP/domain ?

via manualroute?

other options?
