Description Lubomir Kundrak 2007-08-06 14:22:18 UTC
Description of problem:

A new version of dovecot was issued, The announcement (see URL) reads:
	- ACL plugin: If user was given i (insert) right for a mailbox, but
	  not all s/t/w (seen, deleted, other flags) rights, COPY and APPEND
	  commands weren't supposed to allow saving those flags. This is
	  technically a security fix, but it's unlikely this caused problems
	  for anyone.

Version-Release number of selected component (if applicable):
