The general rule of thumb is to always use the DNS and SMTP relay of your immediate upstream provider anyways.
Yup but this is a serious pain in the *ss if you work constantly from a laptop like I do. You'd have to change the settings every time you move.
If it is a privacy issue then there are easy ways (for the technically savvy) around it (ie. -L25:127.0.0.1:25).
For the less savvy (like me) who don't use ssh tunnels that much (until now) here is the solution which I had to research today:
Make the following run at boot time and it will establish a ssh tunnel on a non-privileged local port (2525) using a non-privileged local user.
sudo -u localuser ssh -f -L 2525:127.0.0.1:25 -l remoteuser -N mail.remoteserver.com
Set your outbound SMTP for mail sending to 127.0.0.1:2525
