I've got CentOS box running ISPC3. It works quiet well for me, and i got plan but i'm not sure if it will work as i wish, so i have questions. Can i add secondary ISPC3 server (different computer) so they will communicate with each other? I would like to use the secondary one, as: - Backup MX (Postfix/ will ISPC3 support that? Will it import emails/domains from the first server to accept only correct emails?) - Secondary DNS (Named/ will it import zones/domains from the first ISPC3 automatically after inital config?). I would like to achieve situation, where secondary ISPC3 server know, that he is used for backup mx/secondary dns and import what it needs by himself every time data is changed on the first one.
Setting up a multi server ISPConfig setup is explained in the ISPConfig Manual. https://www.ispconfig.org/documentation/ There is also an oldish Tutorial. Search for "multiserver" on https://www.howtoforge.com/. The backup MX server is not explained in the manual. I do remember seeing a Tutorial or maybe forum discussion about that so it is possible. Otherwise what you requiered in your post is supported by ISPConfig and the Manual.
Thank You for answer @Taleman I've got ISPC manual already (i even get them when they are updated to support project) but there is Debian everywhere which make me wanna cry Well Linux is Linux so it's not problem for me. I post that question before checking manual where i did find Named configuration for multiserver. The problem is there is nothing about MX as You said. I believe there is no support for that inside ISPC at all (just like there are no support for multiple IP for sending/receiving emails inside ISPC). Now i got problem. I would like to use ISPC as Backup MX + Secondary DNS. But since i can't i will have to make it Secondary DNS only. I'm wondering if i can add some part to be supported later if email services will be finally good supported in ISPC. But maybe iw ill find that in manual too. Thank You for answer.
Some people have done backup MX with ISPConfig setup. Use Internet Search Engines with Code: site:howtoforge.com backup MX server ispconfig
