Thanks for the posts, Matthew. While Outlook goes much further at blocking extebsions, I have both users, and customers with users, who are turning to the SmarterMail web interface., and I suspect that the number of web interface users will climb with the full deployment of SmarterMail 16.X We alk need to be prepared, especially for custoners who use insurance underwriting, ans,similar types of software to auto-generate policies and their supporting documents - which is what brought to my attention that GOOGLE.COM is now,rigidly enforcing the .ZIO rule... It's all about educating our customers, before they overwhelm our support teams.
