This patch makes it easier to set the mail_options when sending email using the SMTPConnection class. The patch adds support for setting this value on a class instance level and a global level. For example, passing XVERP? to postfix activates variable envelope return path (VERP) delivery. VERP is beneficial when processing bounce backs from mass emails.
