Mail is an incredibly stable product. Along with its stability is an incredibly professional and educated support team always willing to go the extra mile. I have always been completely satisfied whenever I need to reach out to this team and have never not seen resolution in anything I have needed to reach out to them for. Where most application support leaves you waiting, Ipswitch leaves you answered and always up and running.
