I'm handling mail for several domains, let's call them a.com, b.com, and c.com. I have certificates for each of these domains individually via certbot (letsencrypt) and nginx is happy with all of that.
Since I initially configured the site to handle mail only for a.com, my /etc/postfix/main.cf file currently has these two lines:
smtpd_tls_cert_file = /etc/letsencrypt/live/mail.a.com/fullchain.pem
smtpd_tls_key_file = /etc/letsencrypt/live/mail.a.com/privkey.pemBut I see that mail test tools are reporting that MX for b.com and c.com are misconfigured due to an SSL name mismatch. Indeed, this is true!
So I believe I should generate a multi-site SSL cert. I try this:
sudo certbot certonly --cert-name postfix --webroot \
--webroot-path /var/www/a-com -d www.a.com -d a.com -d mail.a.com \
--webroot-path /var/www/b-com -d www.b.com -d b.com \
--webroot-path /var/www/c-com -d www.c.com -d c.comAnd that fails with a bunch of errors like this:
Domain: www.a.com
Type: unauthorized
Detail: Invalid response from
http://www.a.com/.well-known/acme-challenge/IT7-YURAep4bniD9zYpKpdRUBQcgCRJ6FflmZzWQGNg:

.well-known/acme-challenge/IT7-YURAep4bniD9zYpKpdRUBQcgCRJ6FflmZzWQGNgdoesn't exist.
Multi-site + letsencrypt + postfix is a subject that has recently changed quite a bit, so I'm suspecting my web reading is merely leading me astray. It is also entirely possible I've misunderstood things about SSL certificates. Any pointers how to generate (or point to) the certificates that I need to make those who contact my postfix instance happy with their SSL conversation?
Thanks!

You have a problem with your nginx config. It doesn't seem related to postfix et al.
Really off-topic for this list but you could perhaps post your nginx config and logs.

If this is more properly a certbot question, I should ask there. I'd understood from the certbot docs that postfix had developed a postfix-specific certbot plugin, in which case this might have been the right venue to ask. That I hadn't found that plugin was, to be fair, a bit suspicious to me, but it wouldn't be the first time I miss something in front of my nose.

Hello! Maybe try the Postfix list?
Good luck! Reio

Doh, dovecot and postfix aren't actually the same project. This is not my day. You may ignore me, please.

You're using the webroot plugin for the challenge. This is as simple as dropping a file and letting nginx serve it as static content (maybe with try_files). The various certbot plugins for postfix and other apps are for automating the certificate installation and tweaking TLS configuration to match certain recommendations. That's not related to your issue here. You're looking at a challenge failure. You're saying that the file is there but nginx is failing to serve it, that should be easy to fix and once it fix the challenge will pass and your certificate will be issued. You can then install it, manually or otherwise.

You can use 1 directory to create certificates for multiple virtual hosts. Copy the config below to all the virtual host config you want to use in your certificate (or use 'includes').
user@server:~$ cat /etc/nginx/sites-enabled/a-com server { [...]
location ~ /.well-known {
location ~ /.well-known/acme-challenge/(.*) {
root /usr/share/nginx/html;
add_header Content-Type application/jose+json;
}
allow all;
try_files $uri $uri/ =404;
}}
After reloading nginx you can create a new certificate by providing only 1 webroot directory.
user@server:~$ sudo certbot certonly --cert-name postfix
--webroot -w /usr/share/nginx/html
-d www.a.com -d a.com -d mail.a.com
-d www.b.com -d b.com
-d www.c.com -d c.com

Try add in your nginx "vhost" as the first line: Alias /.well-known/acme-challenge /path/to/acme/.well-known/acme-challenge ProxyPassMatch ^/\.well-known !
I have this same error with ProxyPass inside apache vhost which proxying to node application backend. In letsencrypt logs I have this same what you.
