A PHP library of functions designed to handle all of your one-off e-mail needs under a MIT or LGPL license. Instead of relying solely on the mostly broken PHP mail() function, this library directly talks to SMTP and POP3 servers just as a regular e-mail client would. The result is a high level of reliability in delivery of e-mail messages to recipients. Functions like ConvertHTMLToText() and MakeValidEmailAddress() make it easy to do complex tasks such as convert ugly HTML input into beautiful plain-text output and analyze an e-mail address to automatically correct common typing mistakes. All of that while following the various RFCs surrounding e-mail.

• Carefully follows the many IETF RFC Standards surrounding e-mail (RFC822, RFC2822, RFC1341, RFC1342, RFC1081, RFC1939, RFC2045, etc).
• Relatively complete and comprehensive, yet easy-to-use SMTP, POP3, and MIME libraries. Fully MIME and Unicode-aware.
• Easy to emulate various e-mail client headers.
• Rapidly build great-looking, fully responsive HTML e-mails with the included EmailBuilder class.
• SMTP::ConvertHTMLToText() to convert ugly HTML into really nice-looking plain text suitable for multipart e-mails.
• SMTP::MakeValidEmailAddress() to correctly parse e-mail addresses and automatically correct common typing mistakes.
• Has a liberal open source license. MIT or LGPL, your choice.
• Designed for relatively painless integration into your project.
• Sits on GitHub for all of that pull request and issue tracker goodness to easily submit changes and ideas respectively.
