Phpmailer with postfix

Personally I recently set up a server with a postfix to send mail, as the mail server is from my company I did not need to configure an account I just used the address of the server and I'm just sending, which to my need, is great! However, I am sending emails on a page and wanted to style this email using bootstrap and postfix does not allow for its limitations. I found the phpmailer I found very cool and yet again it needs an email account and in my current scenario I do not use an address. Would it be possible for me to configure Phpmailer for sending using my postfix with the current configuration using pop3?
