[done] Third Party Email Providers Poll

It seems to me that both PHPMailer and Swift Mailer would serve the same purpose as the CodeIgniter email class - all are object-oriented solutions to handling email.

I would prefer the CI solution not be an email abstraction layer in the way Query Builder is for multiple databases. Instead, CI Email should be a lightweight class that addresses the basics of using mail(), sendmail(), or SMTP. That would, in the long run, make it easier for users to fully employ any library or API they chose without compromise. It also makes design and maintenance of the CI class a lot less complicated.
