Hello @caothang2609,

The recipients_max and recipients_max_reject options are changeable through the Advanced Editor tab in WHM >> Exim Configuration Manager, however there's no direct integration of these options in cPanel & WHM. Thus, there's no corresponding option to exclude Mailman deliveries from the values you define for those options.

I encourage you to submit a feature request if you'd like to see an option to configure the maximum number of recipients in a single email from the WHM UI (along with the ability to exclude Mailman deliveries from that value):

In the meantime, you may want to consult with the Exim user's mailing list or a qualified system administrator to see if it's possible to develop a custom Exim rule to exclude Mailman deliveries from the recipients_max count:

Thank you.
