I've tried to set up a global email filter to block .co emails which I've been getting a lot of Spam from lately. Typically, if I see spam coming from an email address like [email protected] I'll create a filter to block - "From contains .monster". Can't do that with .co or I'll block .com. However, the dropdown for "ends with" doesn't see to work. So a filter "From ends with .co" I still get the messages arriving in the SPAM folder. So settings on the server are decent at flagging and tagging ***SPAM*** messages so this is just spam box control where I like to keep it so nothing even lands in there either.
