System not sending mails via postfix, despite postfix configured correctly
Issue
After installing and configuring postfix
, when sending mails from the command line using mailx
or other mail programs, they seem not to be sent out by postfix
and are never received by a recipient on a different mail host.
I double checked the postfix
configuration and it looks correct.
