Bugreport: managesieve-login won't start without a ssl-key

[Moritz Fago]

Hello,

If you don’t have a ssl_key and ssl_cert configured in your dovecot config managesieve-login will fail to start with the following error message:  dovecot: managesieve-login: Fatal: Couldn't parse private ssl_key: error:0906D06C:PEM routines:PEM_read_bio:no start line: Expecting: ANY PRIVATE KEY, even if you haven’t enabled ssl for managesieve-login.

Infos according to http://www.dovecot.org/bugreport.html:

P.S I used doveconf -n to generate the config output, the website says you should use dovecot -n, is this an error or intentional?
