Mairix is complaining about:

rw@zeus:~/Maildir$ mairix pparc

Another version of this program produced the existing database!  Please
rebuild.

However, there is no option in mairix -h or in man mairix to rebuild the
database.

Manually removing the database and running mairix works.

If this error is triggered when you run mairix to rebuild the database,
shouldn't it handle "old database format" automatically by deleting it
and creating a new one?

severity 419554 wishlist
thanks

RC, here is a feature request from one of your users via the Debian bug
tracking system.

RW, I'm lowering the severity of this bug to wishlist. I think the
feature should be added but it only shows up on upgrades. In the
meantime, I  can update the relevant documentation to explain that this
can happen and explain what to do. Patches, of course, are welcome.

Regards,
Mako

Changes:

 .
   * Ignore Content-Transfer-Encoding on multipart entities, as RFC 2045
     requires. A bogus quoted-printable encoding on the top-level multipart
     corrupted part headers and hid boundaries containing '=', so such
     messages were not indexed (Closes: #1153100).
   * IMAP: do not require the AUTH=PLAIN capability for LOGIN; check for
     LOGINDISABLED instead (Closes: #958076).
   * Honor TMPDIR when decompressing compressed mboxes (Closes: #666870).
   * Handle an empty stale lock file and name the lock file in the error
     message (Closes: #345358).
   * Name the database file and say how to rebuild it when it was written
     by another version of mairix (Closes: #419554).
   * Switch from single-debian-patch to a quilt series: the configure and
     mairix.1 changes from -1 and the fixes above are now separate DEP-3
     patches under debian/patches.
