Configuring incoming actions
The Incoming Action tab lets you to select what measures the FortiMail unit will take against spam and virus-infected email coming into the domain. This tab also determines which quarantine list to use: personal or system.
 
For more information on determining directionality, see “Incoming versus outgoing email messages” and “Incoming versus outgoing SMTP connections”.
To configure incoming actions
1. Go to Settings > AntiSpam > Incoming Action.
2. Configure the following:
 
GUI item
Description
AntiSpam Actions
 
Tag email’s subject line
Enable and then enter in the With value field the text that will appear in the subject line of the email, such as “[spam]”. The FortiMail unit will prepend this text to the subject line of spam before forwarding it to the recipient.
Many email clients can sort incoming email messages into separate mailboxes, including a spam mailbox, based on text appearing in parts of email messages, including the subject line. For details, see the documentation for your email client.
 
Reject
Enable to reject the email and reply to the SMTP client with SMTP reply code 550.
 
Discard
Enable to delete the message (instead of delivering the email) without notifying the SMTP client
 
Personal Quarantine
When enabled, FortiMail directs spam to the per-recipient quarantine folder. Also configure:
Delete messages after: Enter the number of days you want to keep the quarantined email. Enter a small enough value that will prevent the size of the quarantine from exceeding the available disk space. If you enter 0 to prevent automatic deletion of quarantined files, you must periodically manually remove old files.
This option and Quarantine for review are mutually exclusive.
 
System quarantine
When enabled, FortiMail directs spam to the system quarantine folder.
Note: Both quarantine options cannot be enabled at the same time.
AntiVirus Actions
 
Virus scanning
Scan email for virus infection and take actions defined in “Configuring antivirus action profiles”.
