I'm not so concerned with the single point of failure.
Users will now have to use a proxy to check their email? If they
don't configure the proxy, they aren't getting any virus protection
from the firewall?
I thought it did some sort of deep packet inspection, and just
monitored all traffic that comes in and goes out. However I was
curious exactly how it does this, especially for encrypted traffic
(not encrypted by the fortigate). I thought it can monitor plain POP3
traffic, but what if you are using a ssl cert with your POP3 server,
then it probably wouldn't work.
Or lets say users are connecting to gmail via ssl, the fortigate
wouldn't be able to block file downloads.
