i'm using simple mangle rule for priority eMAIL, and than im seting on QoS
The rule works only when i'm checking email message on phone iphone & android. On PC Win-10 this rule does not make traffic. I've seen on log.

Rule is very simple:

add action=mark-packet chain=prerouting connection-mark=speedtest.net new-packet-mark=speedtest.net passthrough=no
add action=mark-connection chain=prerouting comment=MAIL connection-mark=!mail dst-port=25,110,993,143,465,587,995,57,109 log=yes log-prefix=Mail--- new-connection-mark=\
mail passthrough=yes protocol=tcp

Does anyone know how to fix it up?

Thanks

noob question
fixed

Нички, the connection-mark=!mail in your rule with new-connection-mark=mail suggests that there is something wrong with the whole concept of connection marking. So please post the complete mangle table, and also read this.

Thanks for that, but my rule works well, im shame to tell you what kinde of mistake i've done. If you are intrested i can tell you
