Redmine

I have everything working, but I am unable to retrieve email from my server.

I am getting the error message:
-ERR Plaintext authentication disallowed on non-secure (SSL/TLS) connections.

I am presently running the command:

rake -f Rakefile redmine:email:receive_pop3 RAILS_ENV="production" ssl=SSL host=<ip> username=<user@address> password=<passwd>

I dont see anything in the docs about how to do this, nor do I see how to do it anywhere.
