Hello, I have configured Dovecot 1.2.12 with Postfix 2.6.5 and everything is working fine. But tomorrow I wanted to run IMAP ALCs and from log I found that this plugin is conflicting with parameter mail_full_filesystem_access = yes in my config. But when I set mail_full_filesystem_access = no it stops authorization for postfix with this message: <pasek at valbek.cz>: Command died with
