Pay attention to your screen shot. You have "Match ALL" in lieu of "Match ANY"... I had a similar issue until I realized my I D 10 T oversight :)

@chuy1 if I check "Match ANY", it will not use all conditions in filter I think. For example, it will delete all messages which are not starred.

@René I am confused. The original message states "need to automatic delete all messages older than 30 days". Nothing about it being starred/not starred.

As a work around, in lieu of the action being "Delete Message", change to "Move Message to" and then select the "Trash on @@@@"

BTW, I've had issues with filters not working lately ... as a matter of fact, they are going to my Junk folder in lieu of being filtered

@chu1 this is why I attached screenshot. Tried change "Delete Message" to "Move messages to trash in IMAP", same result. No messages was deleted / moved . Waited for about 40 minutes.

btw it worked fine with my settings. This week I found it stopped to work.

@René I'm having "filter" issues too, mines the junk filter in addition to filters not being applied https://support.mozilla.org/en-US/que.../1408927#question-reply. I'll keep an eye out on this thread, hope someone else can help.

Hello, any news about this problem please? Using 115.1.1 now and filters still don't work fine..

Is the folder you are filtering the inbox? That as far as I know is the only folder generally affected by every 10 minutes filtering.

@Matt: it's folder inside INBOX.

INBOX - folder 1 - folder 2 etc

just found filter works fine if it's checking inbox, sent, drafts. If is setuped to check some folder like Inbox -> MyFolder, it doesn't work.

ONLY the Inbox is currently supported. Not subfolders thereof. See https://bugzilla.mozilla.org/show_bug.cgi?id=1602704

read it yesterday. so sad :/
