    Question sendmail woes


    Hello experts,

    I'm trying to convince sendmail to relay email via an IP address. This IP address dosen't have a hostname, and sendmail bounces emails back.

    This is the message that goes into the error log:
    ... sendmail[1817]: OAA01815: OAA01817: DSN: Host unknown (Name server: 194.*.**: host not found)

    I've tried adding 194.*.*.* mailhost.domain.name to /etc/hosts and putting that in sendmail.cf and HUP'ing it, but still to no avail.

    Please help,
    Neil

    What did you do?
    This IP address dosen't have a hostname
    It doesn't have reverse DNS? That doesn't matter.
    ... sendmail[1817]: OAA01815: OAA01817: DSN: Host unknown (Name server: 194.*.**: host not found)
    Don't obscure important pieces of information in logfile entries when asking for help.

    I've changed the sendmail configuration to relay via an IP address. The machine can no longer send email directly.

    Well... that's why sendmail won't relay, that's the problem. I've tried editing my /etc/hosts file to give the IP address an alias, but it didn't help.

    Why would the IP address and hostname the machine help? It's behind a firewall so wouldn't help you, would it?

    If you think the hostname or IP address will help, I'll post them.
