Review on Outbound Spam Guard (OSG) by Scott Gamache

OSG has been an invaluable tool for us, it's easy set up and very effective at blocking spam emails coming from our clients' domain names. It does take some time getting used to how each feature works but once you've done this then everything runs smoothly! We were having issues with our mail server being blocked by anti virus software which was causing havoc with our client service teams ability to send emails through Outlook as well as webmail services such as Gmail etc. Once we had setup OSG correctly in terms of configuration then there have not been any problems since.
