Backup

Backup is designed to store copies of messages which Kaspersky Secure Mail Gateway saves during processing. Copies of messages are stored in Backup in unreadable format and therefore do not compromise your computer's security.

Kaspersky Secure Mail Gateway places copies of the following messages in Backup:

• Messages to which the Anti-Virus engine assigned one of the status labels and before actions are taken on them.
• Messages to which the Anti-Spam engine assigned one of the status labels and before actions are taken on them.
• Messages to which the Anti-Phishing engine assigned one of the status labels and before actions are taken on them.
• Messages to which one of the following status labels was assigned after content filtering and before actions are taken on them.
• Messages whose senders' addresses have been detected in a custom black list of addresses and before the actions was taken on them.

Copies of messages are placed in Backup together with attachments.

The default maximum Backup space is 7,32 GB. As soon as this threshold value is exceeded, the application starts to remove the oldest copies of messages from Backup. When the amount of occupied space is again below the threshold value, the application stops removing copies of messages from Backup.
