Hello, Does anyone in postfix mailing list have experience using Postifx software for sending bulk emails with TLS encryption? Can you share your experience with me? The amount of bulk email is quite large, normally for marketing purpose. In the past we have been using sendmail bundled with CentOS 6 OS for a few years already. But we need to upgrade our system and one new requirement is to use TLS. So I’m planning on using recent CentOS 7 operating system. But as I look at its repository, postfix and openssl appear to be old versions. Thanks,
