My local city government uses "McAffe Email Encryption". It's not a simple click-to-verify or a greylist or a CAPTCHA. After sending an email requiring a simple response I get an email to sign up for this service. I sign up to actually read the response. There appears to be an option to get this to send email directly, but it then sends another email with a form for a download.
This is an incredibly frustrating process. Is there a workaround or quick way to get this platform to just send me a damn email?
