The ISP for my .com email address uses Barracuda as a firewall to help convince other ISPs that email from them is not spam. Whenever I send something that gets stopped by Barracuda, I am able to contact the Support staff at my ISP to "push through" the suspected spam. They've been helpful in helping me understand why something I sent may have been suspected as spam. Imagine my surprise in discovering that the ESET message added to my emails certifying that it's been searched for security has become such a trigger. It's added after I hit SEND, so I had to search the knowledge base & turn off the message. Thought some of you might find this of interest.
