Mailsleuth Rated 5 out of 5 stars
Take it from an individual who has experimented with this in the past -- it is fantastic! I give it 5 stars easily. If there were 10 stars available it would get all 10.
Joe, (who has contributed not only to the investigative industry, but also to the COMPINTEL industry), has stated...and I quote: "I have another investigator version that I am updating, and will let everyone know when it is ready." I guess Mozilla should add more stars because they will be used!
