Email Authentication
Increasingly, ISPs and email providers are becoming more aggressive with their spam prevention
strategies. In the past few years, many ISPs and email providers have implemented email
authentication technology, which validates the senders of email in order to prevent phishing,
and to allow the sender's reputation to affect email delivery by giving reputable senders
easier access to a recipients inbox, and allowing more aggressive spam filtering/blocking for
disreputable or unknown senders.
To maximize deliverability for its customers, Savicom supports both primary email authentication
technologies:
