[RCU] possible bug in plugins with roundcube 1.2.5

archive 2.4 GPLv3+ filesystem_attachments 1.0 GPLv3+ jqueryui 1.10.4 GPLv3+ managesieve 8.6 GPLv3+ markasjunk 1.2 GPLv3+ password 4.1 GPLv3+ show_additional_headers 2.0 GPLv3+ vcard_attachments 3.2 GPLv3+

is what i have enabled, bug:

when achived prefs is set up sender addresse sorting it can create any folder without any restriction what chars is allowed or not, but here is the problem, roundcube cant move this mails to other folders afterwards :(

iam unsure if its really a dovecot bug or roundcube plugin archive with sender based sorting to folder, in other words will plugin archive respect dovecot allowed chars for folder nameing ?

can others confirm it works or fail ?
