Hi, We are trying to use regex in postmaster filter, but is doesn't work. I don't know if is it a bug, or we use it wrongly. We need to automaticaly close a ticket, which body contains a line with word "Closeable". Only this word is allow in the line. Sample email: To: test@example.com From: me@example.com Subject: This is a test for auto close Closeable Accounted time: 30 min This ticket can be closed. Regex what we are trying to use in postmaster filter: Filter condition: Check email header: Body Look for value: ^Closeable$ Set Email Headers: Set email header: X-OTRS-State Set value: closed successful We tried ^Closeable.*$ but it also doesn't work. ^Closeable works, but this also matches the line "Closeable or not closeable, that is the question...", but this is not allowed by our policy. Can anybody help? Regards, Balázs
