http://dovecot.org/releases/2.0/dovecot-2.0.19.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.19.tar.gz.sig

Hopefully one of the last v2.0.x releases.

- IMAP: ENABLE CONDSTORE/QRESYNC + STATUS for a mailbox might not
  have seen latest external changes to it, like new mails.
- imap_id_* settings were ignored before login.
- doveadm altmove did too much work sometimes, retrying moves
  it had already done.
- mbox: Fixed accessing Dovecot v1.x mbox index files without errors.
