I made the following changes: * removed all references to stunnel. It isn’t necessary in every supported version of CentOS, and in CentOS 5 or earlier it wouldn’t work with anything modern anyway due to OpenSSL being out of date on an unsupported platform and won’t use any modern TLS implementations. * I switched all the commands to use sudo instead of running as root, * I switched it to an example ISP example.com <http://example.com/> instead of the old att.net <http://att.net/> example, and suggested the user research their ISP’s SMTP server. -- Jonathan Billings <billings at negate.org> -------------- next part -------------- An HTML attachment was scrubbed...
