I wondered where I can find fedora information regarding the cert files placed in: /etc/pki directory. Apparently, there is tls/certs/localhost.pem and tls/private/localhost.key; are these two files required? I also noticed that installing certain servers such as sendmail, spamd, imap, ... creates the pem/crl/key certs, but they contain default (otherwise incorrect [example.com]) certificate information? As for sendmail, I cd'd into the certs directory, issued: make sendmail.pem and enabled the SSL in sendmail.mc file, but apparently, I can no longer log into sendmail (Thunderbird keeps requesting the password) in order to send outgoing email messages, so I am wondering if "localhost" is involved somehow? I would like to rebuild these [self-signed] certificates so that they contain correct servers certificates, notably dovecot, sendmail, spamd, .... and lastly "localhost", if this is required? Does anyone recommend a very good site for dealing with the above issues?
