→Postfix + TLS
Let's start with the "sending" SMTP server we have on VM2. Run the following, replacing andrewsmith.org with your own domain name:
<source lang="bash">cd /root/postfix-keysopenssl genrsa -des3 -out andrewsmith.org.key 2048
chmod 600 andrewsmith.org.key
openssl req -new -key andrewsmith.org.key -out andrewsmith.org.csr
