Searching for Barracuda alternatives didn't yield much. Can anyone recommend a good spam appliance like Barracuda?
I want something that will strip bad stuff out like if I have a .txt attachment that is really an .exe. It sends the email but strips out the attachment. I didn't think Barracuda did that.
Update: It should be a commercial product (but thanks for other suggestions for open source.)
Update: Must work with Windows and Exchange.
