I have a web application (Classic ASP) hosted on an IIS 7 windows server. It uses local SMTP to send emails, and some of this emails include attachments.
Is there a way to send this emails encrypted ? If so, wouldn't the recipient require a password to view them ?
Would it be a better solution to have an external portal for emails to which users can login and view any messages they have sitting there ? this way no 'sensitive' information is sent over email ?
What is your view on this ?
