Subject: if there are no custom headers, don't throw a notice that breaks the json result... 
X-Git-Url: https://git.internetallee.de/?a=commitdiff_plain;h=610542c9dcbe86d8e2d824c8b26b12db8dce77c7;p=horde.git

if there are no custom headers, don't throw a notice that breaks the json result (resulting in the compose window not closing, with no feedback, though the message has been sent)
