LinuxQuestions.org - ssmtp works partly

I'm running Ubuntu and I installed ssmtp. It is mostly working. If I specify a TO: address, it works. If I sent to address "root" or any other plain username (e.g., "backup") it works.

But if I address to root@localhost or <anyuseridBelow1000>@localhost, the mail is sent out but the address is apparently not rewritten properly and the mail never arrives (nor do I get any error messages).

I need root@localhost and other system addresses to work because I want to receive all (warning, error, etc.) messages that originate on this server.

This is the log for a mail that is not delivered

ssmtp.conf looks basically like this, but I have tried various settings and nothing seems to change the issue.

Code:

root=user@example.com



AuthUser=username

AuthPass=password



mailhub=mail.example.com



rewriteDomain=example.com



hostname=hostname.domain



UseTLS=YE
