We have the safe unsubscribe feature turned on our virtual ESA appliance and while some times when unsubscribing we are taken to a successful web page message, other times we are not.
I have many that just say Unsubscribing from xxxx@xxxx.com is in progress. Wouldn't you know it never completes and I get junk mail from this sender weekly.
I also had some people report that they get an HTTP 500 page.
How can we get this to work?
