[Dovecot] dovecot user lost entire folder

[Spyros Tsiolis]

Hello kind people,

OK, today is a bad day for me.
A user from a clients' site called early in the morning to inform
me that she lost an entire folder on thunderbird with (naturally)
important stuff in it.

I am trying to find the lost folder, but there is nowhere to be
found.

Any ideas would greatly appreciated.

Regards,

Spyros
