I am moving a customer from an Exchange host. One interesting service I see they get, they get a daily email of emails blocked, not sure if they are blocked because of Spam, AV caught, or both. I would like allow my customers to maybe get a list of emails that went to junk. This thought came to mind because Google's servers are always getting on Blacklists causing a lot of Gmail based emails are getting flagged as Spam. Customer complain because they do not want to go to the web agent and review a Junk folder, I am not whitelisting all Gmail server IPs.

The customer gets an email with the title: Daily Quarantined Message Report

They get an option to release or view the email. Maybe this would be done with some third party service.
