I am attempting the same project.  I was looking at ImapSync and also just drag and dropping from thunderbird.  I noticed that Cyrus rejects any email with "invalid header" if the message has "From " (from_line) as the first line.  From my brief googling it appears the "From " thing looks to be/have been a standard Unix thing and procmail seems to append this into the message also.  Probably why I couldn't get postfix/procmail working with Cyrus, but that made me discover what sieve is. ;-)

I wonder if there some kind of switch in a conf file to make Cyrus accept "From " as a valid header?  This would make the migration much easier.  If not I will have to remove the "From " line in messages that have it.
