It is hard to answer this question without any information on the "it" that 
"always said something like this". That is, what application are you using 
to send e-mail (apparently Ximian Evolution, but I've never used it), and 
how is that application sending it? And what does "222.154.xx.xx" refer to 
... what host has that IP address? And *where* does "it" say this ... in an 
alert box that pops up? In a mail-bounce message? Someplace else?

With so little info, I can only guess really, but my best guess is that you 
are getting this message from your ISP's SMTP server in an app (a Web 
browser, maybe ... I've never used Ximian Evolution and don't know what it 
is) that uses it directly to send e-mail. That SMTP server thinks you are 
sending the e-mail from 222.154.xx.xx and it objects to relaying SMTP 
traffic from that IP address. The "Can't resolve PTR record" piece means 
that the SMTP server is unable to do a reverse lookup of the address (find 
the FQDN associated with it), which might be a DNS problem or might just 
mean that whoever is authoritative for that address hasn't created a PTR 
record for it. (Try the command "host 222.154.xx.xx", with the real address 
of course, and see it it resolves ... I'd try it here for you if you hadn't 
elected to conceal the C and D quads in your report to the list.)

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.

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.
