Discussion

Acrobat Pro DC provides a Webmail capability. This allows users to send PDFs as email attachments using any mail account that supports SMTP/IMAP protocols. In addition to existing desktop email clients, users can now configure these mail accounts by providing User Name, Password, IMAP and SMTP details. The capability allows users to utilize Gmail and Yahoo mail accounts to send PDF files directly from within the Acrobat application. This capability allows the user to by-pass existing email protections provided by DoD email services.
