PHPMailer is a code library to send (transport) emails safely and easily via PHP code from a web server (MUA to the MSA server).

Sending emails directly by PHP code requires a high-level familiarity to SMTP protocol standards (RFC 821, 2821, 5321) and related issues (such as Carriage return) and vulnerabilities about email injection for spamming. Since 2001 PHPMailer has become one of the most popular solutions for these matters on PHP.
