I’m a newcomer to Tor, so please take that into account. :)
I wonder if it is useful to torify (actually, torsocks) programs such as msmtp and offlineimap, which I use to receive and send emails (I use mutt as MUA). The email account is a regular one (no .onion kind of thing), hosted by a big evil company I have no control over (say, for the sake of the argument, a gmail account).
As far as I understand it, the interest lies in preventing people (say, the sysadmin of the wifi network or my Internet service provider) from knowing I’m downloading and uploading emails. But maybe I get something wrong…
Useful? Harmful? Thanks in advance for your explanations.
