Sendmail setup to work with NTL broadband


I'm trying to setup Sendmail on Solaris10, I'm trying to send email trhough my NTL broadband connection but all I'm getting when tring to send is

mailer=relay, pri=750334,, dsn=4.0.0, stat=Deferred: Name server: host name lookup failure

Has anybody previously setup Sendmail on an NTL Broadband connection.

Many Thanks in advance.

1) make sure that you have setup the DNS client correctly for your box, see
    my answer in: http:Q_21573171.html#14955803

2) make sure that you define the mail smart host in /etc/mail/


    # "Smart" relay host (may be null)

3) If you want to setup you box as a mailserver, you need to ask your ISP to
create an DNS record (with MX) for your box.

please read this Sendmail Configuration for Solaris 10:
