PHPMailer - A full-featured email creation and delivery class for PHP. Supports UTF-8 content as well as 8-bit, base64, binary and quoted-printable encodings. Provides SMTP authentication for LOGIN, PLAIN, CRAM-MD5 and XOAUTH2 mechanisms over SMTPS and SMTP+STARTTLS transports. Automatically verify email addresses. Many PHP developers need to send emails from their code. The only PHP function that directly supports this functionality is mail(). However, it does not provide any help using popular features such as encryption, authentication, HTML messages and attachments. Formatting email correctly is surprisingly difficult. There are countless overlapping (and conflicting) standards that require strict compliance with horribly complex formatting and encoding rules - the vast majority of code online that uses the mail() function is wrong, if not unsafe!

PHPMailer msgHTML local absolute path image embedding and Base64 solution
