If you will install IMSS on the same computer that has a Postfix installation, configure Postfix as listed in this section.
Note
Note
The installer does not install an MTA during IMSS server installation. You should already have your MTAs installed and operational. If you install Postfix on the same computer on which you will install IMSS, verify that the Postfix settings are correct. Trend Micro strongly recommends that you install and use the Postfix distributed with your version of Linux. See http://www.postfix.org for details.

Procedure

  • Insert or modify the following settings to /etc/postfix/main.cf:
    default_process_limit=200
imss_timeout=10m
imss_connect_timeout=1s
content_filter = imss:localhost:10025
imss_destination_recipient_limit=200
imss_destination_concurrency_limit=200
