Configuring email archiving accounts
Before you can archive email, you need to set up and enable email archiving accounts, as described below. The archived emails will be stored in the archiving accounts. You can create multiple archive accounts and send different categories of email to different accounts. For the maximum number of archive accounts you can create, see Appendix B: Maximum Values.
When email is archived, you can view and manage the archived email messages. For more information, see Managing archived email. You can also access the email archive remotely through IMAP.
To access this part of the web UI, your administrator account’s:
- Domain must be System
- access profile must have Read or Read-Write permission to the Others category
For details, see About administrator account permissions and domains.

Configuring account settings
The following procedure is part of the email archive account configuration process. For general procedures about how to configure an archive account, see Configuring email archiving accounts. For information about how to use the email archiving feature, see Email archiving workflow.
- Go to Email Archiving > Archive Account > Archive Account.
- Click New to create a new account or double click on an existing account to edit it.
- For a new account, enter its name.
- In Password, enter the password for IMAP access if you want to access archived email remotely.
- In Forward to, if you require it, enter an email address to which the FortiMail unit will forward a copy when it archives an email.
- For Index type, specify whether you want to index the archived email. Email indexing helps to search the email messages in the archives more quickly. You can choose to index the email headers or the entire email messages.
- Enable Email archiving status. If the account is not enabled, you cannot select it in other places where it is used.
- Enable IMAP access if you want to access email archives through IMAP access.
This account name holds archived email. You also use this account name as the login user name if you want to access archived email remotely through IMAP. Do not include spaces in the name.
Configuring rotation settings
The following procedure is part of the email archive account configuration process. For general procedures about how to configure an archive account, see Configuring email archiving accounts. For information about how to use the email archiving feature, see Email archiving workflow.
- Go to Email Archiving > Archive Account > Archive Account.
- Click New to create a new account or double click on an existing account to edit it.
- Under Rotation Setting, enter the Mailbox rotation size and Mailbox rotation time.
- In Archiving options when disk quota is full, specify what the FortiMail unit should do if it runs out of disk space. Select Overwrite to removes the oldest email archive folder in order to make space for the new archive or select Do not archive to stop archiving more email.
When the mailbox reaches either the rotation size or time specified, whichever comes first, the email archiving mailbox is automatically renamed. The FortiMail unit generates a new mailbox file, where it continues saving email archives. You can access all rotated mailboxes through search.
Whenever an archiving account reaches its disk quota, FortiMail may send an alert email to the administrator, if you enable this feature under Log and Report > Alert Email. For details, see Configuring alert categories.
|
You cannot manually delete specific archived email messages. The only way to delete all of the email archives is to format the mail data disk. |
Configuring destination settings
The following procedure is part of the email archive account configuration process. For general procedures about how to configure an archive account, see Configuring email archiving accounts. For information about how to use the email archiving feature, see Email archiving workflow.
- Go to Email Archiving > Archive Account > Archive Account.
- Click New to create a new account or double click on an existing account to edit it.
- Under Destination Setting, select an archiving destination:
- Local (the FortiMail unit’s local hard drive, or a NAS server if you configure a NAS server as the remote storage target.
- Remote (a remote FTP or SFTP storage server).
If you are archiving to the local disk, the disk quota for all the archiving accounts cannot exceed 80% of the total mail partition. If this quota is met, or 95% of the total disk space is used, FortiMail will automatically remove the oldest email archive folder in order to make space for the new archive.
If you are archiving to a NAS server, there is no limit for the local disk quota of all the archiving accounts. But the local quota for a single archive account is limited with the valid range from 1GB to 80% of the total mail partition. The default value is 5GB.
You can also configure how long the archive folders will be kept. Older folders than the specified retention period will be removed. The valid range is 0 to 3650 days. The default value is 0 day, meaning that no archive folders will be removed.
Archiving email from Microsoft Exchange journaling
Microsoft Exchange servers can record/journal email and then send the journaled email to another server, such as FortiMail, for archiving.
For both FortiMail and the Exchange Server to communicate, you must configure both sides. The document only describes the FortiMail side configurations.
To archive the journaled email from an Exchange Server
- Add a journaling source (that is, the Exchange Server). See the below procedures.
- Create an archive account for the journaled email. See Configuring email archiving accounts.
- Create a archive policy to specify what email should be archived. See Configuring email archiving policies.
To add a journaling source
- Go to Email Archiving > Archive Account > Archive Journaling Source.
- Click New and configuring the following:
|
GUI item |
Description |
|
Host |
Enter the IP address or host name of the Exchange server. |
|
Sender |
Enter the archive email sender address. Note that this is not the sender address in the email messages being archived. It is the email account that sends out the journaling email on the Exchange server. |
|
Recipient |
Enter the email account that receives journaling email on the FortiMail server. On the Exchange server, you must also specify this receiving account. Note that this is not the recipient address in the email messages being archived. |
