I run an unmanaged centos server and have recently updated all domains to https:// with no real problems but in the process I found odd links to an expired certificate that was on the server when I leased it that has stumped me!
Letencrypt provides 4 x .pem files that work but Dovecot seems to use .key and .crt files.
As this is all new to me even for a command line user, help please.
There are 3 entries:-
etc/pki/dovecot/certs which include
Then at /root/watchetwebdesign.co.uk directory includes
(not the same files in pki I think)
Then etc/ssl/certs directory includes
All I need to do is use the current certificate for server.watchet.net
or update this version of the wwd cert.
