I am working on a email confirmation for a website and I am really new to this. So if anyone please kindly show me how to set up postfix to send out mail. I only need to send out mail (Plain text is fine, although encrypted mail would be a plus). I am using Java to send out mail. Please help please
To interact with SMTP authentication on other hosts, you'll need dovecot. Use a sample configuration similar to the one specified below and modify mydomain and myhostname accordingly to your needs. This should allow for basic mail-sending functionality. Use gnupg for encrypting email, I think there should be some Java bindings somewhere.
