Sendmail Offers Domain Keys Software
Sendmail and several other companies, including Yahoo, Cisco and AOL, have been working on DKIM standards for more than a year. The technology lets senders to cryptographically sign message headers, allowing e-mail recipients to securely verify message senders.
Corporate customers are testing Domain Keys for their internal mail systems, said Richard Kreysar, CEO of Sendmail, San Jose, CA, rather than marketers sending commercial e-mail to consumers.
"We see corporate America using this initially," he said. "We have the ability to secure inbound and outbound traffic within your company."
