The office lan has zeroshell like gateway and dns. There is a specific domain for which I have to use the smtp and smtpbkp. I created two a record smtp.mydomain.com 18.104.22.168 smtpbkp.mydomain.com 22.214.171.124 And a record MX mydomain.com MX smtp.mydomain.com (priority 30). I can’t create a second MX record mydomain.com MX smtpbkp.mydomain.com (priority 10). because I get ‘ERROR: ldap_add: Already exists (68) ‘. Is it wrong what I’m trying to do, or is wrong the way I’m doing it? Thank you. Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
