Hi Egoitz,

from this line:

> sarenet.es!user.egoitz version 10

it seems that you have not run a reconstruct on the mailbox (should be
version 13 on cyrus 3.0)

try:
reconstruct -V max user/[email protected]

As you are probably coming from cyrus version 2.3 reconstruct is going
to take a long time ...

I guess the unexpunge problem is also related and you need to
reconstruct the mailbox.

Cheers,
Javier
