dovecot - Nov 2011 - Invalid "doveadm search" queries not rejected

Hello,

I think I've encountered a bug in Dovecot 2.0.9 (as provided on CentOS
6).

According to the doveadm-search-query(7) manual page, a "mailbox"
specification can only come at the beginning of a search query. However,
if I put a mailbox specification in the middle of a query, not only do I
not get an error message, I get surprising results:

  $ doveadm search mailbox A |wc -l
  6979
  $ doveadm search mailbox B |wc -l
  206
  $ doveadm search mailbox A OR mailbox B |wc -l
  42492

If it became possible to do boolean logic on mailbox queries, that'd be
cool. But barring that, these invalid queries should be rejected.

Relatedly, if I can only do simple mailbox filtering, does anyone know
of a clever way to efficiently emulate more complex boolean logic?

Please CC me on any replies as I'm not subscribed to the list.

Thanks,

Peter

It doesn't exactly say that, but yeah, it doesn't also include MAILBOX
and MAILBOX-GUID as search keys. Added now to future versions.

I'm pretty sure this was fixed in v2.0.14.

It is.
