I wrote this fix to avoid obviously specifying that I am using a mobile device
to reply to an email.
Others want this for ease of filtering messages from their host by Message-ID.

Instead of interpreting a "-" at the beginning of a line as
an error response, consider the absence of a "+" at the
beginning of a line as an error response.

The problem arises with godaddy servers spewing additional
lines of data upon login failure. The login was being
interpreted as successful, and a STAT commanded was subsequently
being sent, resulting in a dialog saying 'Cannot connect to
server. (Invalid int: "auth_error:")'.
$ openssl s_client -quiet -crlf -connect pop.secureserver.net:995
...
+OK <24984.1394317012@pop.secureserver.net>
user testuser
+OK
pass testpass
testuser not found in the auth database
warning: auth_error: authorization failed (no such object)
-ERR authorization failed Check your server settings.
Some IMAP servers are broken and don't correctly handle string
literals with the LOGIN command.
This switches to using quoted strings instead.
This is what Thunderbird does.
