Bi-directional email message scanning in MTA

Bi-directional email message scanning mode allows the user to scan inbound and outbound email messages with the same implementation algorithm. The bi-directional content filter method is MTA dependent. ESET Mail Security comes with five content filters that are built for the most common MTA programs, such as MTA Sendmail, Postfix, Exim, QMail and ZMailer and GroupWise Internet Agent (GWIA).

Check that your MTA is properly configured and running. Then, configure ESET Mail Security for bi-directional email message scanning by running the following script:


Select MTA and content filter install options. The ESETS module being used is also displayed.

Note that the installer backs up all modified configuration files and can display every command that it will execute after your approval. The backup configuration files should be reimplemented after uninstalling. Detailed steps for all possible scenarios are described in ESETS setup and configuration topic of this documentation.
