Let me start off by saying I found the articles with references to Crossbox and logging in with admin@domain which I have done, however there is no “Administration” section listed. I also tried with the “default” user as well
EDIT: I found the answer to my question about Roundcube vs Crossbox
server.mxrouting.net vs mail.mxlogin.com for the CNAME
My original question remains about Crossbox & the admin user - additionally if using Roundcube there is no SSL certificate???
Thanks
