Enhanced Email Sink with Port & SSL

I needed to add support for Port & SSL for [Office 365.](http://office.microsoft.com/en-us/outlook-help/settings-for-pop-and-imap-access-for-office-365-for-business-or-microsoft-exchange-accounts-HA102908389.aspx#_Toc383167843)

But rather than adding the parameters throughout, I decided to introduce a new class that should make adding new options easier.

This is my first pull request, so let me know if anything needs to be changed.

Thanks for a sane logging library! :+1:
