[Dovecot] lmtp_rcpt_check_quota not working

[Bernhard Schmidt]

Hi,

Dovecot 2.2.9 (Debian package from backports) does not seem to respect
lmtp_rcpt_check_quota

protocol imap {

protocol lda {

}
protocol lmtp {
  mail_plugins = quota sieve
}

so Dovecot should reject in RCPT TO phase, but according to the logs of the 
upstream Postfix it does so after END-OF-DATA

(host xxx[2001:xxx] said: 452 4.2.2
<user at domain.de> Quota exceeded (mailbox for user is
full) (in reply to end of DATA command))

I haven't seen any commits regarding to this in 2.2.10 or tip.

Bernhard
