Google have introduced DomainKeys Identified Mail (DKIM) for their Apps customers to help curb spam.
“Today, we mark another notch in the spam-fighting belt: we’re making it possible for all Google Apps customers to sign their outgoing messages with DKIM, so their sent mail is less likely to get caught up in recipients’ spam filters. Google Apps is the first major email platform – including on-premises providers – to offer simple DKIM signing at no extra cost. Once again, the power of the cloud has made it possible for us to bring this feature to millions of customers quickly and affordably.”
Google Apps administrators can enable DKIM signing in the “Advanced Tools” tab of the control panel.
