10-ssl.conf: Unknown setting: ssl / debian 1:2.2.13-12~deb8u

[Sophie Loewenthal]

Hi,


I've been trying to get dovecot2 running and kept having this error message:

May 13 13:38:32 mail systemd[1]: Started Dovecot IMAP/POP3 email server.
May 13 13:38:32 mail dovecot[2178]: doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/10-ssl.conf line 61: Unknown setting: ssl

# openssl version
OpenSSL 1.0.1t  3 May 2016

This package is from from Debian repos with version number 1:2.2.13-12~deb8u amd64

In case I had inadvertently entered some invisible charaters in 10-ssl.conf, I deleted and typed this out. Not copy-pasted: 
# >10-ssl.conf
# cat 10-ssl.conf
# echo 'ssl = required' >10-ssl.conf
# echo 'ssl_key  = </etc/ssl/private/xxx.key' >>10-ssl.conf
# echo 'ssl_cert = </etc/ssl/private/xxx.pem' >>10-ssl.conf

I’ve done usual searching online for a week and read some dox, but cannot see what I’ve missed out. 
 Any ideas? Please?

Thanks,
Sophie
