MarsEdit and SSH
Secure Wireless Email on Max OS X was incredibly enlightening. I've long been suffering from SSH ignorance. Thanks to that article, I locked up my POP3 and IMAP email accounts. Then Daring Fireball casually mentions that he uses, "...SSH tunneling not just for email, but for posting to Movable Type with MarsEdit as well." In a flash of inspiration, I think I figured it out. I am an SSH neophyte, so your mileage may vary. I tested using MacSniffer. It looks like my sessions were encrytped, as I couldn't see my username and password in clear text, as I could without SSH tunneling.
In SSH Tunnel Manager (SSHTM), I added a new local redirection to a tunnel I already configured for IMAP mail access. I set the LAN Host to be my domain. I set the remote port to 80, which is the default port for http. I arbitrarily mapped the local port to be 1431.
In MarsEdit, I replaced my domain in "RPC URL" with "localhost:1431". 1431 is the local port I specified in SSHTM.
That's it. Make sure you've started your tunnel in SSHTM, and you should be all set, posting securely via MarsEdit.
Update: This was origninally written for Movable Type, but it will obviously apply to any blogging system using the XML RPC. Thus, I made the post a bit more generic.
