You can do this with retry rules like the following example:
yahoo.com rcpt_421 F,24h,6h
That is - for all messages for recipients in the yahoo.com domain which
receive a 421 response to a RCPT command, park them in the queue for 24
hours and only try every 6 hours.
I highly recommend familiarising yourself with the retry configuration:

It will very likely do exactly what you need without any external
"assistance".
