The issue occurs due to any of the following scenarios:

• You are using an SMTP server that requires authentication.
• WFBS may not be automatically updating its configuration file even after you have configured the correct SMTP settings in the console.

To resolve the issue:

1. Back up these files:
• ..\PCCSRV\ofscan.ini 
• ..\PCCSRV\Private\ofcserver.ini
2. Open the ofcscan.ini file using a text editor like Notepad.
3. Under the [INI_OUTBREAK_ALERT_SECTION] section, type the following lines:

   Outbreak_Alert_Enable_SMTP=1
   Outbreak_Alert_SMTP_Server=[place your SMTP server here]
   Outbreak_Alert_SMTP_Port=[place your SMTP port here]
   Outbreak_Alert_SMTP_Send_To=[place the email addresses that should receive the notifications]
   Outbreak_Alert_SMTP_Send_From=[place the administrator's email address here]

4. Look for the [INI_STANDARD_ALERT_SECTION] and type the same lines you added in Step 3.
5. Under the [CAV_INI_SESSION] section, type the following lines:

   CAV_SMTP_ENABLE=1
   CAV_ALERT_SMTP_SERVER=[place your SMTP server here]
   CAV_ALERT_SMTP_PORT=[place your SMTP port here]
   CAV_ALERT_SMTP_SEND_TO=[place the email addresses that should receive the notifications]
   CAV_ALERT_SMTP_SEND_FROM=[place the administrator's email address here]

6. Restart the Trend Micro Security Server Master Service.
