I agree that this might happen. We must remember that the wiki is written mostly by 
people that have been working with dovecot for many years. I think you referred to
this page: https://wiki2.dovecot.org/Quota so I fixed the syntax. The correct syntax
was in the https://wiki2.dovecot.org/Tools/Doveadm/Quota page already.

you can change this setting:

plugin {
  quota_status_overquota = "552 5.2.2 Mailbox is full”
}

to give 4xx SMTP error code instead to force the MTA to retry for up to 48 hours as mandated
by the RFC.

you can also return quota_rules from usertb. The simplest way depends on what kind
if userdb setup you have.

User iteration must work in order for that command to work. Making user iteration to work
once again depends on what kind of userdb/passdb setup you have.
