Dear Maintainer,

I use icedove for connection my email provider via TLS IMAP connection.

If I copy and paste a mail to dolphin window dolphin opens an window asking for
a password for the mail user I use in dolphin.

I checked now with tcpdump -i eth0 -A port imap2 the network traffic and was
surprised, that I can read my password in clear-text form so any user who watch
the connection can steal my login credentials.

There is no warning in icedove that the password will send in clear-text nor a
setting how I can disable this simple imap support to prevent me from such a
problem.

Please extend the the imap support for full encryption connection to a imap
service.
If not possible please allow to disable the use of imap service in dolphin.
