Hi Digital Ocean Community,

I've been monitoring my server over the last few days and i've noticed that the top process within memory is (constantly) smtp at 56.32% is this high or something I should be worried about? If so how would I go about debugging this? Im happy with terminal commands.

Server Running Ubuntu 16.04.3 x64 and has a small number of Wordpress sites running with serverpilot

Thanks for your help!

Thats odd!

Why don't you check the mail server logs? (you might find the logs under /var/log/mail/*)
Plus, check the SMTP traffic via tcpdump in order to monitor the normal traffic flow. You may be under attack.
