How to make Exim send out emails faster

Difficulty rating: 1/5

I believe this is the precise purpose for the "Email delivery retry time" option in WHM Tweak Settings and change to 1M

In WHM, go to Home » Service Configuration » Exim Configuration Manager » Advanced Editor

How to make Exim send out emails faster


Configure the following settings to their respective values:

smtp_accept_queue_per_connection = 0
split_spool_directory = true
queue_run_max = 15
remote_max_parallel = 15
deliver_queue_load_max = 6

ignore_bounce_errors_after = 2d


Note: Setting queue_run_max to 0 will set it to unlimited/infinite, this will risk your server's load and memory.
