Hi.
I have a trouble. When user in local network trying to send messages using any mail-clients, that messages will not sending very long time.
Message (5mb) can standing in outgoing folder 20-30min. If message size higher than 5mb, it will be send after 1-2 hour or more.
How I can to set high priority for smtp from local network?
Here is one way:
add action=change-dscp chain=forward new-dscp=7 port=25 protocol=tcp src-address-list=“SMTP”
Be sure to add the appropriate address list.
