Hi, Seems like your sendmail is not configured to be send/relay mails of authenticated users only. check how to configure /etc/mail/access. this file allows you to control which users or hosts will be able to send / relay mails from your sendmail.
hope this helps. can you share your sendmail.mc file if thats not the case. regards, viket On Mon, Sep 1, 2008 at 7:41 PM, Vikrant Telkar <[EMAIL PROTECTED]> wrote: > I don't think this is server problem.
