Archiving for compliance and governance
Save local, incoming, outgoing and relayed messages. Integrate easily with third-party archiving solutions and non-rewriteable media for legal compliance. Use Kerio WebMail, an IMAP client or a third party legal discovery tool for auditing.

Retention Policy
Conserve space and prevent excessive storage of old information by automatically deleting old email items.
Flexible retention policy options allow administrators to configure mail retention policies per individual domain, or per user. Select which folders to include in the policy and set the age of items to be deleted in days or years.
