It is dreadfully slow -- I used it to export some of my users' mailboxes to Gmail or other remote mail servers, and I could almost cut&paste the messages faster. Like Aki

It's not supposed to be human readable -- the point of this exercise was to check whether your indices are really out of date. You can perhaps compare the mtime of the index files and the mailbox.

Might need to download and build it. Do you know any other way of getting it? Thanks Kevin A. On Thu, Jan 29, 2015 at 3:34 PM, Joseph Tam <jtam.home at gmail.com> wrote: > Kevin writes: > >
