Im not that good at firewalling with the MT yet, will this rule stop all outgoing port 25 traffic that does not come from my mail server(192.168.238.253)?

chain=output src-address=!192.168.238.253 protocol=tcp dst-port=25
action=drop

I was told to block all outgoing mail not comming from my mailer by CBL http://cbl.abuseat.org as they have me on there blocked ip address list.

thanks alot guys

No, chain=output is for outgoing traffic originating from the MikroTik router itself, no coming from other devices behind the router that are sending outbound traffic through the router. You must use chain=forward for this.

Other than that your filter rule looks OK.
