Cyrus mailbox (plain files) to Dovecot

[Miloslav Hůla]

Hi,

the simplest way is to create cur/new/tmp folders for every mailbox and 
copy all mailfiles into new folder. Dovecot will create all other files 
like 'dovecot-uidlist' automatically. You may get some warnings.

All emails will be marked as new ones and all will be redownloaded.
