MY FIRST QUESTION IS: can multiple domains and multiple
SSL certificates share one IP address? I can rent more
IP addresses, but I hope to avoid complication and cost.
Why not apply several domains to one IP? One that with scripting will
automatically renew every 60 days?
I do this to:
Certificate Name: michaelsnet.us-0001
Domains: michaelsnet.us
Expiry Date: 2020-06-11 23:30:00+00:00 (VALID: 80 days)
Certificate Path: /etc/...fullchain.pem
Private Key Path: /etc/...privkey.pem
Certificate Name: michaelsnet.us
Domains: michaelsnet.us jamhome.us lists.michaelsnet.us
michaelrasmussen.org michaelrpdx.com orrandonneurs.org saunter.us
www.jamhome.us www.michaelrasmussen.org www.michaelrpdx.com
www.michaelsnet.us www.orrandonneurs.org www.saunter.us
The only problem I had with it was figuring out what to do when I
deleted two domains. That was easy as it turned out.
NEXT QUESTION: what is a good ten page summary of how to
set up and maintain SSL certificates in the simplest way?
Ditto for DKIM, and configuring postfix for both.

Over the years, I've accumulated many domains and URLs
on three web servers and multiple companies. I've spent
a few days simplifying and debugging all that.
After transferring dirvish to a new maintainer, I've
consolidated everything else onto one offsite virtual
server with one IP address. 14 domain names point at
that IP address, all with the same domain registrar.
About half of the domains send email. For example, the
wiki websites notify page authors that their page has
been modified.
Without SSL certificates, some of the major email services
(like gmail) automatically route my outbound emails to user
spam folders. Not helpful.
I don't really understand SSL certificates, or DKIM, but
those can establish the bona fides of my mail server with
the big services. Both my name registrar and my virtual
server hosting provider offer free certs ... I think.
If I need more information, I can websearch the buzzwords
in the summaries, or pester the rest of you. The better
the summaries, the less the pestering.
