Checking the email queue via SSH will allow you to acquire valuable information. For instance, a high email queue may be the reason your server is experiencing high load.
Use this command to find the number of emails in the queue:
exim -bpc
Example:
root@fakeserver.dizinc.com(~)$ exim -bpc 58
Use this command to see the number of emails in the queue and print out their name, destination, and source:
exim -bp
Example:
root@webgo.com.au(~)$ exim -bp
