Hi @andreas-doehler,
For MTA your refer to the Mail transfer agent right that is the same for the postfix configuration.
I just have this configuration on my Master, it is necessary set the same configuration for all my Slaves?
I’m asking because unfortunately for these slaves I can’t access for the network configuration to set the rules in the another applications for the notifications, or maybe just creating the postfix rules on the server slave is necessary.
Thank you for your time!
