Unable to block email address in Frontend

[emmi]

Hello, I'm trying to block notification+zrdo6pzre=gz@facebookmail.com in the "Server Spam Blacklist" window in the Frontend but it seems it's not being saved, the window is always empty. Can someone verify this?

That is not a valid email address. The = symbol is not allowed in email addresses. That is why the address is not accepted in the blacklist.

Regards,
Sarah

Well, it's what's in the logs.

That may be, but it contains invalid characters. You can try blocking it in exim although there may be problems with that as well.
