I an running CentOS7 in a docker container. I need to send email from that container so I installed sendmail and then I run: m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf` and when I try and send mail it fails with: larry.martll at gmail.com... Connecting to [127.0.0.1] via relay... larry.martll at gmail.com... Deferred: Connection refused by [127.0.0.1] Anyone know how I can configure sendmail so that I can send mail?

It has 20+ answers and all are different. I have another container running debian buster and in there I do" yes yes | sendmailconfig and then I can send mail. But I don't see sendmailconfig in CentOS7. Is there an equivalent?

Enable the service if you want it to start at boot time.
