I'm no longer able to send my alert pics to my Gmail account.  This is just like the problems described in
 DViewCam Email Stops on Windows 10  http://forums.dlink.com/index.php?topic=65173.0Try using NetZero as a Gmail workaround.  NetZero must not have yet implemented the same security feature that Gmail is using.  I created a NetZero account.  Now I'm able to sign into NetZero to email my alert pics to my Gmail account.
I'm using:
 SMTP Server smtp.netzero.com
 Port 465
 E-Mail Sender (my Gmail address)
 Check SMTP server needs authentification
 Check SSL
 User Account (my NetZero e-mail address)
 Password (my NetZero e-mail password).
Please let me know when D-ViewCam corrects their Gmail interface.
