dovecot - Aug 2019 - Sieve redirect

What is the intended way to configure Sieve for the redirect command? 
Can I do it using in Dovecot (e.g. using the submission config) or does 
it have to be done in sendmail?

I'm running Dovecot in a container and the MTA/MSA is in another container.

Dovecot version: 2.3.2.1 (0719df592)
