mail works, but sendmail doesn't! (Postfix)
I installed postfix on a server and when I send an email with the sendmail command it doesn't get delivered, but when I send with the mail command it does get delivered. What's worse, postfix logs claim it got delivered when using:
This is what the logs show for echo "test email" | sendmail [email protected]

Obviously it looks right. But no mail ever gets delivered. But this one: echo "test email 2" | mail [email protected] works great! The mail gets sent!
So I don't understand why in the world them mail command works, but not sendmail. Any idea?
Solution 1:
Ok, let's test it direct:
$ host -t mx mailinator.com
mailinator.com mail is handled by 1 mail.mailinator.com.
mailinator.com mail is handled by 1 mail2.mailinator.com.
➜ ~ telnet mail.mailinator.com 25
Trying 23.239.11.30...

Hello. This is a test message.

This works, as the message can be seen in https://www.mailinator.com/v4/public/inboxes.jsp?to=sendmail
Your log shows that the message with id 38418406Ehas been sent as well, and that the remote server accepted this mail.
So just try it again, it will work.
