Hi Timo,

I just realised from the e-mail I sent earlier, the output of FETCH 32 
FULL and FETCH 32 BODY[TEXT] are not the same. They are referring to 
different messages.

a1 fetch 32 full

I had to delete the dovecot.index.cache file for it to work.

Is there anything I can do to help with the debugging? The tricky part 
is that this is a user mailbox, so I may not be able to have control 
when e-mails get deleted.

Cheers.
