Re: [Postfixadmin-devel] Backup MX with Postfixadmin

[Michael N. <ne...@ne...>]

@Janfred I assume both your mail servers are accessing the same DB backend?
or are you replicating the information somehow  from the primary to the 
DB on the second mail server?

@Janfred @Fongaboo: would you mind moving this discussion (back) to 
Fongaboos posting on Github
https://github.com/postfixadmin/postfixadmin/discussions/713#discussion-4904766 
?
I personally love mailing lists, but most users are found there.

I believe there is a number of users interested in this topic, since 
this is one feature that postfixadmin is still lacking.

Cheers
   Mike
