Question:
Could you provide a full list of email systems (or protocols) that Win2PDF integrates with?

Answer:

Win2PDF also supports an optional add-on called the Win2PDF Mail Helper that implements an SMTP mailer and integrates with the Win2PDF "Send PDF" user interface and registry developer interfaces.  The Win2PDF Mail Helper application is free, and can be downloaded from the following page:
