I didn't answer above because I haven't decided.

Questions:

Does either Pro or community support user created auto responders to answer mail automatically with a msg?

My reading indicates LDAP is more featured than the MySQL version. I have never deployed LDAP, is there a long learning curve or will iredmail set it up and just allow me to use it. I have to deploy fast.

It looks like on my host that only CentOS (and eventually Rocky) has a backup application. I've  set up on Ubuntu several times (I jumped CentOS ship on the 8 change). Is there an advantage to either OS other than AppArmor seems to work out of the box and SELinux will take some fussing (done it, very familiar with adding permissions)?

Thanks.
