WP Mail SMTP SendGrid Edition

This plugin reconfigures the wp_mail() function to use SMTP instead of mail() and creates an options page that allows you to specify various options.

You can set the following options:

• Specify the from name and email address for outgoing email.
• Choose to send mail by SMTP or PHP's mail() function.
• Specify an SMTP host (defaults to localhost).
• Specify an SMTP port (defaults to 25).
• Choose SSL / TLS encryption (not the same as STARTTLS).
• Choose to use SMTP authentication or not (defaults to not).
• Specify an SMTP username and password.

Also adds subject to headers for SendGrid Activity Screen. SengGrid is a powerful SMTP service, however it's Activity Log screen misses the message subjects. Our plugin adds that back in!
