Quick question: With Dovecot (or other LMTP servers) does this
detect over-quota conditions? The Postfix verification probe does
not send any message data, just "MAIL FROM", "RCPT TO" and then
"RSET" + "QUIT" (or perhaps just "QUIT").
So if the LMTP server does not reject "RCPT TO" for over-quota
recipients, the probe will only confirm recipient existence. Of
course an LMTP server should ideally detect over-quota before
message transfer begins, so perhaps Dovecot and other implementations
do that.
