This is one of the actual rebounce report ( I tried sending from several
machines/senders/places ), from the system administrator :

Your message did not reach some or all of the intended recipients.

( 222.124.xxx.xxx is off-LAN address )

In a rebounce report. In other reports, it mentioned other IP address if I
sent to other name addresses.

I think you are right, but, I can't prove. Pinging to 222.124.57.160, just
didn't resolve the name. All sent, no loss. OK, but, no real name . . .

I didn't conceal, it's just that I forgot ( remember, I was sending the
e-mail from outside machine in other place ).

( this time, I'm sending via my windowz, with SMTP server authentification
checked in outlook )

Hmmm ... well, I can't resolve it either, and your problem is that
whatever host is issuing this bounce report (you left that part out) is
unwilling to relay (forward mail to another domain, that is) from whatever
IP address it sees your e-mail as coming from.

If 222.124.57.160 is **your** off-LAN IP address ... that is, the address
your router NATs LAN hosts to ... then the problem is that you are using a
mail forwarder that will not relay for that address.

If it is not your NATing address, then I don't have enough information to
suggest anything concrete ... except to observe that you don't have a Linux
problem per se, but some sort of an authentication problem with whatever
SMTP server your e-mai client uses to send mail.

The problem may be with the true lack of the referenced PTR record ... an
error indicating a misconfiguration by whoever (probably some ISP) is
authoritative for that IP address.
