For example I need to send an email from my PC to another email I use perl with sendmail module. I use public email server to send my emails. Should I make a local server? I just need to edit some MIME headers before sending: there're 4 headers "Recieved:" how could I change them??? oh "X-Mailer:" and "X-Message-Info:" too? I actually don't care what software to use, I just want to send email with changed headers.
