Original Press Release:

CanIt 7.0.8 Anti-Spam Software Released

Roaring Penguin Software upgrade includes support for Domain Key Identified Mail (DKIM) and Vouch By Reference (VBR)

OTTAWA - Roaring Penguin Software Inc., the email filtering experts, makers of the acclaimed CanIt-PRO, CanIt-Domain-PRO and Hosted CanIt anti-spam solutions, announced the release of CanIt 7.0.8.

New security features in CanIt 7.0.8:

1. CanIt now has built-in support for DKIM (DomainKeys Identified Mail). DKIM is a method for senders to securely indicate the domain which takes responsibility for an email message. DKIM can prevent attackers from forging the source domain of their messages. CanIt users who choose to use DKIM to validate the origin of a message can use information about the signer as an additional measure to limit spam, spoofing, phishing, or other undesirable behavior. See for a description of DKIM.

2. CanIt now has experimental support for Vouch By Reference (RFC 5518). Vouch By Reference, or VBR, is a protocol for adding third-party certification to email. Specifically, VBR permits independent third parties to certify that a certain domain's DKIM signatures or SPF records should be trusted to indicate legitimate messages. Roaring Penguin Software is a leader in enabling their customers to adapt IETF standard protocols to the real world of spam fighting. As protocols like SPF, VBR and DKIM become widely used they increase the likelihood that spam will be detected and that valid mail will make its way safely into the recipients' inboxes.

3. CanIt 7.0.8 also includes improvements to outbound rate limiting, fail-over, and reporting.

CanIt 7.0.8 is available as:

  • CanIt-PRO, an anti-spam software solution suitable for small and medium business

  • CanIt-Domain-PRO , spam filtering software for MSPs to host anti-spam for their customers.

  • Hosted CanIt, a fully outsourced, hosted spam service.
