I am trying out various PHP CMS systems and have yet to be able to communicate with email. I need to know the settings necessary (PHP, Apache, Mercury or other mailer module) to get this working. This might be simple once I have my site on a real webhost, but I just don't understand how phpmail(), sendmail or SMTP work. I'm assuming it is possible to set this up on a local test system.
Please assume that I know next to nothing about this aspect of website programming. Is there a tutorial somewhere that would explain it?
Thanks in advance.
