I get many emails with answer for another email with subject: Re: Normal subject and sent with CC to some emails lists CC: When I use 'Create a filter rule' for a message with right mouse I get only Automatically By From By To By Subject But I do not have this one By CC And get these messages not filtered and in normal Inbox folder. Could you add by Creating filter rule one field for CC? I use this for FreeBSD Developers email list and other similar Condition: to matchcase "developers@FreeBSD.org" | to matchcase "developers@freebsd.org" | from matchcase "<developers@FreeBSD.org>" | header "Sender" matchcase "owner-ports-developers@FreeBSD.org" Action: move "#mh/Mail.Claws/Operativni sistemi/BSD/FreeBSD/FreeBSD Developers" When I use to_or_cc it works, but one rule for CC is needed. Please add this to http://www.claws-mail.org/manual/claws-mail-manual.html#handling_filters
