How do I REJECT one recipient in a catchAll domain?

[SubZero5]

Hi,

I have set up a catch All domain account. But I want to filter out a couple of email addresses and do not want to accept emails sent to those accounts. How can I make a domain virtual alias to REJECT at the SMTP transaction with 5xx error code with a custom message?

Can someone please lead me to the right direction?

Thanks..

email accounts can use SIEVE filters which can be easily managed from the roudcube.
