Certs (again)

[John Borhek]

OK, sorry to be dense, but I am just not understanding how to implement 
certs so I can actually use Thunderbird or some other mail client. I 
don't personally care about authoritative certs (but I will get them if 
required and already have a GoDaddy UCC which includes 
smtp.mydomain.com) but I need the server to identify itself correctly, 
not as localhost.localdomain

Here are my steps:

[root at smtp ~]# cd /etc/pki/tls/certs

[root at smtp certs]# make smtp.mydomain.com.pem

<Input data as required>

[root at smtp certs]# vi /etc/imapd.conf

<change from: tls_key_file: /etc/pki/cyrus-imapd/cyrus-imapd.pem to: 
tls_key_file: /etc/pki/tls/certs/smtp.vmsources.com.pem>
<changefrom: tls_cert_file: /etc/pki/cyrus-imapd/cyrus-imapd.pem to: 
#tls_key_file: /etc/pki/tls/certs/smtp.vmsources.com.pem>

[root at smtp certs]# vi /etc/postfix/main.cf

<change from: smtpd_tls_key_file = /etc/pki/tls/private/localhost.pem 
to: smtpd_tls_key_file = /etc/pki/tls/certs/smtp.vmsources.com.pem>
<change from: smtpd_tls_cert_file = /etc/pki/tls/private/localhost.pem 
to: smtpd_tls_cert_file = /etc/pki/tls/certs/smtp.vmsources.com.pem>

[root at smtp certs]# service cyrus-imapd restart
[root at smtp certs]# service postfix restart

And then no log in to Roundcube!
