Swift is a fully OOP Library for sending e-mails from PHP websites and applications. It does not rely on PHP's native mail() function which is known for using high server resources when sending multiple emails. Instead, Swift communicates directly with an SMTP server or a MTA binary to send mail quickly and efficiently. Swift is comparable to PHPMailer except that it implements an extremely flexible plugin system meaning you can get the most out of sending emails from your PHP applications. The interface for Swift is both tighter and more intuitive. ** Works with Gmail secure servers!! ** This is free software, licensed under the LGPL.
