How to get exim to send email faster

Here are some settings which can be used to get exim to deliver mail in a quicker fashion.
Unless otherwise stated, they are options which can be added to the top section of the /etc/exim.conf, followed by an exim restart.

1)  Tell exim not to queue messages which have a lot of destination emails in them.   The default is 10.
Setting this to 0 will get exim to try and deliver all of them without saving them to the spool/queue.
A value of 0 can be dangerous, as it may bog down your server.
If 0 (unlimited) isn't for you, then try something like 100.


2) Ensure your spool directory is split into sub-folders.  The default exim.conf should already have this enabled.

split_spool_directory = true

3) Tell exim to run more sending processes at the same time:

queue_run_max = 15
remote_max_parallel = 15

Note, you can set queue_run_max = 0 to set it to be unlimited, but again, this runs the risk of bogging down your system.
Adjust these values to meet your needs.

4) Exim provides a guide on how to use a RAM Disk, if you happen to have one available:
