Hi all, I have followed the instructions in this article to get sendmail working, which, so far has worked but when I look at /var/log/mail.log I have the following error

<snip>, dsn=4.0.0, stat=Deferred: Name server: host name lookup failure

Anyone have any ideas?

    OK, i think it had nothing to do with that entry I made in /etc/hosts but because I had added my ISP's DNS servers in the DNS server list in the network control panel, I tested this by removing those and the problem recurred even though I had an entry in /etc/hosts but I was able to resolve the issue by adding them again.

    I had the very same issue with sendmail when I tried to set it up recently. I had all but given up on it to wait for my Panther distribution but I was tidying up some settings on my Mac for a recent LAN renumbering when I fixed it by adding an entry for the local IP address in /etc/hosts file. I am not sure why this worked and it implies that sendmail's message was misleadingly not indicative of some problem with the destination IP but the local host IP.

    Your DNS is not set up properly -
    this can have various reasons -
    maybe you are not connected to the internet when sending -
    there are severeal solutions to this, depending on your newtork-environment -

    tell me more about your set-up and i guess i will find the solution.
    you might be able to solve this by just using the /etc/hosts - file and/or the mailertable in a home environment.
