*Exclusive* keeps sending me spam marketing emails - but each has a slightly different domain name getting thru the block domain option. I did not see a way of specifying *exclusive* as the domain name to mark as junk. Is there a way to do this?
You can do it by creating a Rule to use with words found in the header.
Go to Menu > Tools > Rules, and create a new Rule.
Type in From: exclusive
This is a wildcard search, so any occurrence of exclusive in the from address will be a positive.
