Set mail to only display mail within 30 or 60 days, Here are two examples.

1. normal E.g:

A654 FETCH 2:4 (FLAGS BODY[HEADER.FIELDS (DATE FROM)])

• 2 FETCH (FLAGS (\Seen) BODY[HEADER.FIELDS (DATE FROM)] {73} Date: Tue, 07 May 2020 12:26:55 +0800 From: <test@www.chengmail.ml>

Is there any way to display the result of case 2? I found lua. https://doc.dovecot.org/admin_manual/lua/#mail-lua But I don't know how to edit the lua script, Are there more examples? I also watched the help, but it doesn't help much. https://doc.dovecot.org/configuration_manual/authentication/lua_based_authen... https://doc.dovecot.org/configuration_manual/push_notification/#lua-push-not...

Can Lua fulfill my needs?
