You can adjust the frequency of your Barracuda Quarantine Digest. You will need to login to your Message Security Settings by clicking the Manage Quarantine button from your most recent digest.
The first screen allows you to set the times when digests will be sent:
Simply, click the hours you wish, and the block will turn blue. To remove the schedule, just click the block again and it reverts to empty.
Once you have made your changes, simply click Save Changes in the top right hand corner of the screen.
How the Quarantine Digest Works
The quarantine digest only goes out if new quarantined mail is saved in the user’s folder since the last notification cycle. Each day the quarantine notification service runs for all users. If there is no new quarantined mail for a user since the last notification interval, or if a user has logged into their account since the last notification interval, no quarantine digest will be generated and sent to that user for that same 24 hour period. Note also that links in the quarantine digest for viewing, delivering, whitelisting or deleting a message from the quarantine inbox expire in 5 days from the date the digest is sent out.
