Google provides a non-SSL server I have been using with my M20i for some time. It only works sending to gmail addresses and I haven't tried it with Google Apps yet.
From the Google Groups site: "If your device does not support SSL, connect to aspmx.l.google.com on port 25" . Regular login rules apply.
You can also try using STunnel (www.stunnel.org) to use as a relay. I've never used it, but if you're a bit geeky I hear it's not tough to set up.
Have an M20i with 2.1 network firmware. Wanted to know if anyone has figured a solution for using scan to email (we use Gmail) since my machine does not support SSL in it's current state? Does newer firmware offer this feature? Is there another work around that I do not know about.
