    Sendmail (stupid?) question


    Hello there.

    This may be a stupid question, but it's quite important as of now...

    Can you send email to a machine connected to the Internet BUT which doesn't have a domain number, just a static IP address?

    i.e.: username@xxx.xxx.xxx.xxx

    Is it possible? At all? I've tried, but the mail is always bounced with a "550 Host Unknow" error.

    TIA.

    You can do this if and only if the target machine has an smtp daemon running. This daemon must be set to receive mail from your IP/hostname and port 25 must be open to the target.
