If not, the "mail" command probably just submitted the message into postfix's outgoing mail queue, and it will remain there until postfix is started.<BR /><BR />If postfix was running, read the mail log in /var/log to see what happened to the message. <BR /><BR />Did you try to send to a local username? Then the mail should have ended up in the local system mailbox at /var/mail/<USER> unless you have configured something different.<BR /><BR />If the mail was rejected, you might also have the bounce message in your local system mailbox. It usually lists the rejection reason in plain language.<BR /><BR />MK</USER> Thu, 03 Mar 2011 08:28:09 GMT https://community.hpe.com/t5/operating-system-linux/hi/m-p/4760582#M43839 Matti_Kurkela 2011-03-03T08:28:09Z
