How do I use TLS/SSL with Qpopper?
• Obtain Qpopper 4.0 or later. • Obtain and install a TLS/SSL library. Qpopper works with the free OpenSSL package as well as SSL Plus and Security Builder® from Certicom. • Compile Qpopper. If you are using OpenSSL, add –with-openssl to the ./configure command. If you are using SSL Plus and Security Builder® add –with-sslplus to the ./configure command. • Make sure your system has /dev/urandom. Many systems already do. You can usually obtain one from your vendor. Lack of a suitable /dev/urandom will severely compromise security. The Entropy Gathering Daemon can be used as a /dev/urandom device. After installing it create a startup script that runs egd.pl /dev/urandom. • Create and install certificates.
