Maybe rh.com is baulking at the www. as a =>way to filter out would-be spammers. => =><<JAV>> RedHat is rejecting all mail from servers which are on a dynamic address pool. Personally I think it stinks. If you're running sendmail just add these two lines to your /etc/mail/mailertable lists.redhat.com esmtp:smtp.your.isp redhat.com esmtp:smtp.your.isp and then rebuild your db. No restart of sendmail is required. And by the way, the error message used to be more descriptive. Telling us that we need a "valid mail server" is considerably less descriptive than saying that all mail from a dynamic IP address pool is rejected. => =>---------- Original Message ----------- =>From: Paul Gillen <gillen1951@xxxxxxxxx> =>To: Red Hat User List <redhat-list@xxxxxxxxxx> =>Sent: Thu, 13 Nov 2003 12:11:13 -0800 (PST) =>Subject: Mail error: reason: 550 5.0.0 You must use a valid mail server => =>> A home-hobbyist tries to set up sendmail.
