I have set up fail2ban and Postfix configured with DKIM to send me mails and it works except I would like to get my mails encrypted.
I found this tutorial:
sudo postconf -e ‘home_mailbox = Maildir/’
sudo postconf -e 'mydomain = benjaminthompson.org
sudo apt install letsencrypt
sudo letsencrypt certonly --standalone -d benjaminthompson.org
And I get:
Problem binding to port 443: Could not bind to IPv4 or IPv6.
And find this:
But I don’t know what to do. Any help wil be much appreciated, thanks!
there runs a webserver or something else on port 443. You can’t use standalone mode if there is already something on that port
Since you already have a certificate for your domain ( benjaminthompson.org ) you can use that certificate for postfix - or are you trying to obtain a certificate for a different domain ( possibly mail.benjaminthompson.org )
I would love to use the same certificate benjaminthompson.org to postfix.
How do I do that?
Just follow the section for “Setting up SMTP authentication” in the link you provided in your first post.
