You can use the attached sample email message to test your sendmail configuration which should help you troubleshoot. Here are the steps:
1) add all the recipients to the sample email message (one per line - e.g. `Bcc: person1@domain.com`)
2) modify the reply-to and from addresses
3) send the sample email message via sendmail -t < example-message.txt
4) see what happens, and debug accordingly
Please make sure to verify your settings by sending a test message before running this script!
