SSL Certificates with iRedMail
From KlavoWiki
SSL Certificates
Generate the certificate request: OpenSSL_CSR_with_SAN
Once the certificate has been generated and the certificate downloaded from SSLForFree copy the certificate public and private keys.
cp certificate.crt /etc/pki/tls/certs/iRedMail.crt cp private.key /etc/pki/tls/private/iRedMail.key
Reboot or restart all the different associated services. Reboot is easier here.
Load SSL modules
From linux shell
a2enmod ssl
