If you run the
dovecot -n command on CentOS 7.x based Virtualmin system, then it will give the following warning messages:
doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:104: ssl_ca_file has been replaced by ssl_ca = <file
The issue is addressed by replacing
ssl_ca_file = /etc/webmin/miniserv.chain
ssl_ca = /etc/webmin/miniserv.chain
Still would be nice if this is fixed in your repositories.
