Dovecot can now internally report these failures:
/* Temporary internal error */
MAIL_ERROR_TEMP,
/* It's not possible to do the wanted operation */
MAIL_ERROR_NOTPOSSIBLE,
/* Invalid parameters (eg. mailbox name not valid) */
MAIL_ERROR_PARAMS,
/* No permission to do the request */
MAIL_ERROR_PERM,
/* Out of disk space or quota */
MAIL_ERROR_NOSPACE,
/* Item (eg. mailbox) doesn't exist or it's not visible to us */
MAIL_ERROR_NOTFOUND,
/* Tried to access an expunged message */
MAIL_ERROR_EXPUNGED
I also added quota_full_tempfail setting to control if it should return
EX_TEMPFAIL or bounce the mail. All other errors are treated as
EX_TEMPFAIL.
