On a related note.. I use Bitdefender business email security. But this also applies to Sophos Email Security, or something else like it. When you receive an email, all links are replaced with links that bounce through the gateway, which downloads the page first and looks for malicious redirects, scans it for malicious fingerprints, etc. Then it shows you the chain of redirects and there's a button to actually proceed to the site. On some sites, they require you to login to activate the account, and this scan eats up the activation token. So when you click through, it errors up like "this token is already used", and you can't activate your account anymore on the real visit. Happens on enough sites to be annoying.
