Removal commands

Remove email from a specific sender.

for i in `exiqgrep -f sending@email.com -i`; do exim -Mrm $i; done

Changing the exim deliver load setting

Well, as you probably know, you really need to resolve the load issue as any changes to exim to force it to process are only going to exacerbate the situation. AFAIK, the setting you want to change is:

   deliver_queue_load_max

Which by default is set to 3. If you go into WHM > Exim Configuration Editor > Advanced Mode > and put this into the first textbox and Save:

   deliver_queue_load_max = 6

Then the queue will process up to a load average of 6 instead of 3.
