Hi

Someone know how I can reduce exim cpu load when a user send a lot of legitimate email.

My cpu load is between 1-2 and when some users send a large mail list I have a cpu load spike to 30-40.

No matter that emails will be processed a little more slowly.

Any help ?

Thanks in advance

queue_only_load 	queue incoming if load high
queue_only_load_latch 	don’t re-evaluate load for each message
queue_run_max 	 	maximum simultaneous queue runners
remote_max_parallel 	parallel SMTP delivery per message
smtp_accept_max 	simultaneous incoming connections
smtp_accept_max_nonmail non-mail commands
smtp_accept_max_nonmail_hosts 	hosts to which the limit applies
smtp_accept_max_per_connection 	messages per connection
smtp_accept_max_per_host 	connections from one host
smtp_accept_queue 	queue mail if more connections
