Spam and Viruses
All messages sent via Gaggle Mail are scanned for spam and viruses by powerful industry-leading scanners. Any message which is flagged as spam or containing a suspicious attachment is bounced back to the sender asking whether the message is actually genuine, 99.9% of the time we never hear back from the sender since the message was correctly flagged.
Our spam filters are highly accurate with very, very little spam getting through, and as far as we know a virus has never been successfully sent via Gaggle Mail.
