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.
