So I have been spending way too much time on my new mailserver instead of other work. The howto do date is: http://medon.htt-consult.com/Centos7-mailserver.html This is all hand-coded html. I have learned a bit, and any tips are accepted. Some inconsistencies where I learned something, and did not go back and change all occurrences. I still need to USE postfixadmin to create a domain and a user. Then test postfix and dovecot and roundcubemail. I still have to configure amavis, clamav, spamasssassin, and maybe mailgraph.... Any review is appreciated. Bob
