[rt-users] [Sendmail] mail delivery problem

[Sivan DERAY]

Hi,
 
Here is my problem:
 
my machine is named : support.
this machine is seen as support.domaine.com
 
When i'm trying to send mail i've got messages like : 
 
Jul 12 06:56:01 support sendmail[21968]: i6C4u1K21968: to=.,
delay=00:00:00, mailer=local, pri=0, dsn=5.1.1, stat=User unknown
Jul 12 06:56:01 support sendmail[21968]: i6C4u1K21968: from=root,
size=48, class=0, nrcpts=2,
msgid=200407120456.i6C4u1K21968 at support.domaine.com>
, relay=root at localhost
Jul 12 06:56:01 support sendmail[21971]: i6C4u1K21968:
to=sivan.deray at free.fr, ctladdr=root (0/0), delay=00:00:00,
xdelay=00:00:00, mailer=relay, pri=60048, relay=mailsw.domaine.com.
[172.16.30.20], dsn=5.7.1, stat=Service unavailable
Jul 12 06:56:01 support sendmail[21971]: i6C4u1K21968: i6C4u1J21971:
DSN: Service unavailable
Jul 12 06:56:01 support sendmail[21971]: i6C4u1J21971: to=root,
delay=00:00:00, xdelay=00:00:00, mailer=local, pri=30148, dsn=2.0.0,
stat=Sent
 
Every outgoing email are relayed to mailsw.domaine.com
The problem is that for the ISP (here FREE) i'm seen like
ROOT at SUPPORT.DOMAINE.COM and SUPPORT.DOMAINE.COM is an unknown
subdomain.
 
I tried to changed the outgoing domaine name from
root at support.domaine.com to ticket at domaine.com, it seems not change
anything apart for some isp that do not check for the validity of the
incoming domane name.
