PEAR's Mail package defines an interface for implementing mailers under the PEAR hierarchy. It also provides supporting functions useful to multiple mailer backends. Currently supported backends include: PHP's native mail() function, sendmail, and SMTP. This package also provides a RFC822 email address list validation utility class.
