comment Automatically defer certain messages in Postfix
@Kromey A strange but acceptable work around is to log entries to a central syslog server. There you analyze the flow of mails. If it gets suspicious, disable the login for that user. Or apply firewall rules (as long as you are allowed to do that on the appliance).

comment Elasticsearch is using way too much disk space
Logs are not really repetitive. User A logs in at time 1. User B logs in at time 2. What is repetitive? Both tuples have to be indexed and stored separately. In addition to the log entry itself.

Did you ever consider the overhead it takes to store and index that data? This is where the difference comes from.

You did a restore instead of a reboot.

comment Can I mount a read-only btrfs volume across multiple machines?
Absolutely! This is the way to go. Containers (better instances) are "stateless" and meant to run-stop-drop.

Oh, so you are referring to the container storage and not the data volume storage. Latter one could be on any FS.

Why not just mount a NFS? Or DRDB?

Do you mean their inbound or outbound servers? They are not the same.

comment Postfix message ID originating process?
@AndersBraünerNielsen no it makes no difference. The id you are referring to is called the Queue-Id. The Queue-Id is totally random and not related to any source information.

comment Postfix: Enforcing outbound TLS based on sender and receipient domain?
The first option does not work. Even if the MUA uses TLS to communicate with the gateway MTA, the ongoing nexthops are not automatically TLS secured. And Roadgeeks wants to talk to the nexthops with TLS based to the sender.

comment Send one invalid email response to sender
I didn't get your configuration. Probably because you didn't provide one. Your solution - as far as I understood it - is to disable catch-all. Dropping mail does not discourage spammers. Instead it encourage them to send you more.
