[Evolution] Recover IMAP email from local copy

[ev trauco neverbox com]

Hi All,

I accidentally deleted all my email from one of my IMAP accounts.
However, I've always have a local copy of my email and happen to have
one from a few weeks ago, which I'd like to import back.

So I have an old .evolution folder with the local copies
under .evolutoin/mail/imap etc etc. I've tried to import single files
using the 'import' function, but it doesn't work. Does anybody know how
to accomplish this?

Thanks,
Carlos
