      Hi,
      i'm have some problems with my out going email settings. (OCS10G-R1 on Linux RH 3 update 5)
      am receiving emails from any where but i can't send emails to some domains.
      and here is some examples:

      domain/ send to/ receive from
      yahoo.com/ ok/ ok
      hotmail.com/ ok/ ok
      gmail.com/ ok/ ok
      sofrecom.com.ar/ not working/ ok
      cpsps.org.ar/ not working/ ok

      and i cann't figure out the reasone.

      i didn't find any errors regarding the sent emails to the unreachable hosts in the log file.

      the problem is that after i send the message, i get a failiure delivery message

      From: "Mail Delivery Subsystem" <MAILER-DAEMON@ocs.lempert.com.ar>
      To: <claudio.pereira@lempert.com.ar>

          Testing your SMTP connection to the remote host without using an email client:

          Example as follows:
          ============================
          - do a telnet to the remote_host on port 25

          telnet mail.sofrecom.com.ar 25
          --> ehlo sofrecom.com.ar

          250-AUTH PLAIN
          250 HELP
          --> mail from:claudio.pereira@lempert.com.ar

          --> test
          --> .

            Now lets try from the OCS email server using "telnet localhost 25" as follows:

            Testing your SMTP connection to the local OCS Email server to realy your outgoing message:
            ============================
            - do a telnet to the localhost on port 25. This is your OCS email server.

            telnet localhost 25
            --> ehlo hereIam
