Hello, @robert,

The SubstituteMaxLineLength value is typically used in the Exim mail server configuration rather than the WHM (Web Host Manager) interface.

To modify the SubstituteMaxLineLength value in Exim, you can follow these steps:

1. Login to your server via SSH as the root user.

2. Open the Exim configuration file using a text editor such as vi or nano. The location of the file may vary depending on your server setup, but it is usually located at /etc/exim.conf or /etc/exim/exim.conf.

3. Search for the line that begins with “substitutes” or “substitute” in the configuration file.

4. If the line does not exist, add it to the configuration file.

5. Add the “max_linelength” parameter to the substitutes configuration line, as shown below:

substitutes:
driver = plaintext
max_linelength = 5000

6. Save the changes to the configuration file and exit the text editor.

7. Restart the Exim service to apply the changes. You can do this by running the following command:

service exim restart

After completing these steps, the SubstituteMaxLineLength value should be set to the value you specified in the Exim configuration file.

Alternatively, please try to reach out to your hosting provider for further assistance on this matter.

Kind Regards,
8Themes Team.
