Q2:
given the minuscule work-load, is there any preference/preclusion
between employing the 'usual' x86 processor or 2 Arm Ampere

You should check if the software you want to use is available
for the desired platform. Distributions might provide dovecot
packages for ARM while the official dovecot repository might
not. Then you would have to compile the sources yourself.
This ^^^^^. Specifically if you want to run an EL distro there are good
choices that offer ARM support and come with stock postfix and dovecot
packages, but if you want to run the GhettoForge packages (which have
newer versions of Postfix and Dovecot than that offered by the stock
distros) then I'm afraid you're stuck with x86_64 for now. Similarily
you might have issues with other supporting software that is only
available from 3rd-party repos or where 3rd-party repos have newer
versions taht you want to use, but not for ARM.
Yes, I was following-through with the earlier advice, and noted the same.
No, I'm content with being part of the herd (as distinct from using
Hurd), preferring stability and knowing that reliability can be hard-won!
I'm torn between RHEL (as a developer-member they give me numbers of $0
licenses), and one of the lighter rpm/yum/dnf distros. The former has a
stated commitment to Arm CPUs - which means I could (relatively) easily
set-up a server and try a load-test...
Further to earlier comments, re: distress at being forced to upgrade: in
the interests of fairness it is a previous major-version of Postfix
running on an older CentOS.
(not mentioned because I'd deserve any pointed criticism!)
'The plan' presumed that the hardest part of the process would be going
through the docs to see what needed to be removed/changed and to take
advantage of improved services - TLS/encryption first out of the gate.
Following personal recommendations (from elsewhere), I was looking at a
couple of the 'super-packages' which bundle Postfix, Dovecot, and RDBMS,
in with a bunch of 'other stuff'. The virtues of Containers to the fore.
However, most would require perhaps twice the RAM that my existing
combination doesn't even fully occupy (thus marginal-cost/benefit
implication).
New to me was Docker Mailserver. This appears to be more cut-down, but
also gives (me) the impression that main.cf and master.cf are either
hidden-away or totally-inaccessible. Nr1 difference is 'no RDBMS', which
I guess I could live-with (am quite at-home with SQL and such) and don't
need it for (eg) the web-site side of things, so...
Do you have experience using this package?
(is it sufficiently "Postfix" to be suitable conversation on this list?)
