My director wants to block webmail access from internal clients. He asked specifically for blocking AOL, Yahoo, Hotmail, Comcast, Verizon, but I know more will be coming.
Is there an easy way to accomplish this? The only way I can think of is to get an account on those sites, check the URL's they use for mail reading, and blocking them. I expect that to take a while, so if there is an easier way I would love to know it.
Thanks for any help,
