Publisher review:Swift Mailer is a fully OOP library for sending e-mails from PHP websites and applications. Swift Mailer 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.
Early versions of Swift were comparable to PHPMailer. Swift has since evolved and matured into a fully-fledged object-oriented mailing solution.
Compared with PHPMailer, the interface for Swift is both tighter and more intuitive.
Swift supports event-driven plugins which offer you the opportunity to really take control of the library and set this mailer apart from everything else that's out there.
Over time, and from previous versions, the library has been steadily refactored and is now usable for more than just the blind sending of emails. It can compose RFC 2822 compliant messages for use elsewhere too. I'm looking at offering the reverse and parsing real emails into the message object format used in the library.
But, Swift is not just an e-mail class. It's a complete mailing library which includes many separate PHP classes which tie together. This offers a tremendous amount of flexibility.
