OT: How to Easily Set Up a Full-Featured Linux Mail Server on Ubuntu 18.04.5 LTS with iRedMail 1.4.0

BIND-Users on topic content first:

I absolutely agree.

How much effective performance difference does the loopback interface 
(lo) vs the local LAN interface (eth0) make?

Similarly, how much effective performance difference does an on host 
instance of BIND make vs across the LAN to another host in the same site 
make?

I absolutely agree that a /local/ /to/ /the/ /network/ caching DNS 
server is a boon for email.  --  Definitely avoid simply relying on big 
3rd party resolvers across the Internet.



Aside:  The rest of my reply gets to ride along and would not have been 
sufficient for a reply in and of itself because I believe it's off topic 
for BIND-Users.

It's interesting.  It's a recent take on one of many ways to host your 
own email.

I saw this message splattered to a number of mailing lists, many of 
which I think the message (content) was rather off topic for the list. 
E.g. what does it have to do with the BIND DNS server installation, 
configuration, and operation, other than the fact that email usually 
relies heavily on DNS service (implementation independent).

To each their own.

Email administration is a massive topic in and of itself, which is 
probably better discussed elsewhere.

I appreciate the recent, as in not months ~> years old article 
encouraging people to host their own email.  Though I personally 
disagree with it or would do things a fair bit differently.
