Content Preservation policies decrease the retention period of messages in the archive, to a value less than your Maximum Account Retention setting. Message content that matches a Content Preservation policy is purged from the archive on reaching the preservation time specified.
There are two versions of the policy, the only difference between them being the length of time that messages are stored:
- Content Preservation (Days): Specifies the number of days that message content is stored in the archive.
- Content Preservation (Minutes): Specifies the number of minutes that message content is stored in the archive.
Consider the following before configuring a policy:
- Content Preservation policies only affect the content of a message (e.g. body, attachments).
- A message is not archived if it has a retention period of three days or less. Instead it remains in the Accepted Email queue until it expires.
- Message retention can be adjusted using Retention Adjustments.

The options are: Option Description The Return Address (Mail Envelope From) This default setting applies the policy to the SMTP address match, based on the message's envelope or true address (i.e. the address used during SMTP transmission). The Message From Address (Message Header From) Applies the policy based on the masked address used in the message's header. Both Applies the policy based on either the Mail Envelope From or the Message Header From whichever matches. When both match, the specified value the Message Header From will be used.

Source IP Ranges (n.n.n.n/x) Enter any required Source IP Ranges for the policy. These only apply if the source IP address used to transmit the message data, falls inside or matches the range(s) configured. IP ranges should be entered in CIDR notation.
