[Dovecot] new flags in Maildir files

[Giuliano Gavazzi]

I think the problems is around line 436 of

http://www.dovecot.org/tools/courier-dovecot-migrate.pl

as it reads the dot dirs after having read :list in the previous block  
of code. So, the content of the directories is appended to dovecot- 
keywords.
I know nothing of perl! So I cannot really understand why it is so and  
how to fix it...
(Note that this error happens on BSD systems, that is MacOSX and  
FreeBSD, I might run it on a Linux virtualbox as a cross test, just in  
case it is a perl platform quirk).
