Excuse dopey question.
I'm not exactly clear about certificates.
Apache2 default install has this snake oil certificate
Can make a new one for apache
Can make one for dovecot
Can make one for ssl
Is there supposed to be the one (self signed ) certificate pair in one
place for the machine that each process hands out ?
Can they be moved to another machine ?

Apache, dovecot and Postfix can all use the same certificate, you do
need to configure each one to the location of the certificate though.
SSL is something else: apache, dovecot, postfix are all
services/programs. SSL is a protocol/way of encryption. Self-signed
means there is no Certificate Authority backing the legitimacy. Getting
a Let's Encrypt certificate (I recommend certbot) will get you a
legitime certificate, but only for the hostname (e.g.
web01.yourdomain.com) you provide it. This must be traceable to your
machine through DNS, so moving it to another machine would only work if
that machine would completely replace the old machine (domain name) and
the DNS is changed to point to your new IP address (or the old machine
gets taken out of 'the air' and the new machine gets the old one's IP
address).
Best.
