To use SSL or TLS to encrypt SMTP, POP3, IMAP or HTTP connections requires an SSL certificate. This article describes how to generate your own self signed SSL certificate. A self signed certificate will not cost you any money, but the certificate will not be automatically accepted as trusted by the email client or web browser.
yum install crypto-utils
genkey --days 365 mail.acme.localReplace 365 with the number of days you want the certificate to be valid and mail.acme.local with your own domain name.
