Well, since Eric asked me to put it in here, i put it in here:
I want to use a vps as a master for cloudmin / virtualmin administration and would also like to give it a second job as a backup mx.
Do you have a standard procedure for that?
Does it make sense, of installing first virtualmin to get things going with all mail related stuff like spamassasin, clam av etc and the configure the mailserver for backup purpose and then installing cloudmin or doing it manually?
What do you think about letting postfix check rbl lists? Would that reduce spam too? I've read quite a lot about this, but i do not want to mess up ;-)
One could think it a bit larger, of having a Mailserver who would filter all mails centralized for a bunch of other servers behind. Here are a lot of options possible, which one could use, but not all of them give you what you bet for, so what do oyu think, which way to go, if one has not only one virtualmin based webserver, and Cloudmin Pro too... Also, creating a best practice for mailserverhandling, also with certs and encrypted client communication (port 465, 587) but also hardening it PCI wise and using PFS, would be a larger task to accomplish. So, should we go down this road? Perhaps we find some thinkgs, which could be done in virtualmin to make life easier?
We will see. ...
Thanks and best.
