Subject: email: Simplified the logout / quit functions
X-Git-Tag: upstream/7.37.1~1965
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4838d196fdbfcc3e8779ff4416ec5d0d35561172;p=platform%2Fupstream%2Fcurl.git

email: Simplified the logout / quit functions

Moved the blocking state machine to the disconnect functions so that the
logout / quit functions are only responsible for sending the actual
command needed to logout or quit.

Additionally removed the hard return on failure.
