Multidomain / IP Address Setup (Dovevot 2.2.10 on CentOS7 ) is failing: Fatal: Couldn't parse private ssl_key: error:0906D06C:PEM

Hi Ed,

Interresting setup. I like the way you striped it all down to just one 
single file :-)

But can you explain why you use globally:

ssl_cert = </etc/ssl/dovecot.pem
ssl_key = </etc/ssl/private/dovecot.pem

and certs for any additional Domain each?

##
local_name mail.pettijohn-web.com {
   ssl_cert = </etc/ssl/mail.pettijohn-web.com.crt
   ssl_key = </etc/ssl/private/mail.pettijohn-web.com.key
}
##

I configured it the way you do, but within the default 
/etc/dovecot/confd structure but
i had no luck. I testet local_name (SNI), local, local <IPv6> (dedicated 
IPv6 Address but had no lock

Configinfo:
1) MTA (Postfix 2.10.1) and MDA (Dovecot 2.2.10) configured on IPv6 
Addresses
2) The MTA and MDA are connected to MariaDB (the default MySQL 
replacement on CentOS7 now for virtual domains, users, passwords, aliaes ect
3) Postfix uses Dovecots SASL Implementation and Postfix and Dovecot 
talking via LMTP and UNIX Sockets.
