Slightly off-topic.
My bottom-of-the-line VPS is being deprecated. Making me grumpy because
it has been working so well (+updates) for all these years!

Q1:
can an email server be run off IPv6 (exclusively) these days, or are
IPv4 + v6 alternatives necessary?
You need IPv4, if you have remote users. IPv6 would be fine
for internal usage, though.
Thank you (both).
Q2:
given the minuscule work-load, is there any preference/preclusion
between employing the 'usual' x86 processor or 2 Arm Ampere processors?
Both offer Linux. Cost is effectively same.
You mentioned a VPS, which means shared hardware, i.e. unused CPU
resources are not really unused, they can be used by someone else.
So, there's no particular advantage to staying with the traditional
x86-style model, nor to moving to the newer Arm-based offerings?
Linux is offered on both, but am wondering if there is possibly some
processor to work-load (mis-)matching beyond my understanding...
(yes, appreciate the irony that the concern may be 'efficiency' -
despite the fact that the Postfix server is by no means challenging
current capabilities - and the Cloud-Host assures me that the (two) new
choices offer superior performance to the existing set-up)
Yes, understand that if one is sharing with some 'hog', our
under-average demands will still be disadvantaged by the
averaging-algorithm. However, it's cheap 'n cheerful...
