Not sure if this is the right group, but since we have Exchange 5.5 I will start here.
I am currently using Trend-Micro's Interscan Messaging Security Suite as an SMTP gateway to provide content filtering and virus protection, the SPAM filter catches a LOT but we are still getting 15-20 messages per user per night that slip through.
I noticed that my ISP recently switched to a SPAM filter that auto-responds to any message sent to my home email account and requires the sender to click on a link and manually enter the text displayed in the box to authorize that FROM: address as valid. I wondered if there are any products like this for the corporate world that I could use as an SMTP gateway...
Thanks in advance.
