Dovecot `ssl_ca_file`

In your maillog, at /var/log/maillog, you may see a warning error similar to this:

server dovecot: config: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:104: ssl_ca_file has been replaced by ssl_ca = <file

This is easily fixed in Webmin by going to Webmin > Servers > Dovecot IMAP/POP3 Server and clicking the [Edit Config Files] button:

On the line number indicated in the maillog message, you should see a line similar to this:

ssl_ca_file = /etc/webmin/letsencrypt-ca.pem

Comment out that line, and then copy & paste it with ssl_ca_file replaced by ssl_ca such that the lines should read, thus:

# ssl_ca_file = /etc/webmin/letsencrypt-ca.pem
ssl_ca = /etc/webmin/letsencrypt-ca.pem

Now, click the[Save and close] button.

Finally, click [Apply Configuration] to apply your changes.

Job done!
