You need to understand the consequences of your change on exim in
/etc/exim/exim.conf - in particular what qualified domain names you expect to
receive mail on. If this is not changing, I think you are probably OK
(although you just might have to change things like
receiver_unqualified_hosts=
and
local_domains=
)
I this ssh will be fine (I have transported some of my key pairs to different
machines and they still work).
Are you running a nameserver (such as bind) then you will have to change that
to reflect your change.
