dovecot - Feb 2022 - On mailbox full, retry for 4 days or similar instead of reject

Howdy,

I don't know if this is dovecot specific and i guess it may not be at 
100% so I ask for help.

I want postfix not to discard the message imediatly when a mailbox is 
full, i mean when postfix tries to deliver it to dovecot lmtp.
Is it possible to change the behavior to something like what postfix 
does when he tries to deliver a message to an external server and the 
server is unaccessible for 4 days (the default i guess), and if in that 
period discard it.

Does this exists? At least i know gmail does something similar to this.

I've tried to google a bit but didn't found info that could lead me to 
this configuration.

Thanks in advanced,
Jorge

How do you signal postfix that the mailbox is full?
How much over quota do you want a mailbox to be allowed to go?
Whats your running config, please show doveconf -n

if you set "quota_full_tempfail" to "yes" in dovecots
lda.conf, it
should answer with a temporary failure-code 422 instead of permanent
522. (at least the code of lmtp_local_rcpt_reply_overquota() says so)

as lmtp is similar to smtp, postfix or any other MTA should honor this
and keep the message in queue until the temporary failure goeas away or
the queue-timeout (in Postfix!) is reached.
