The mail exchanger of freebsd.org is a bit strict about the hosts that it accepts mail from. In an effort to stop at least some of the spammers that might plague the mailing lists of freebsd.org, the mail server accepts mail only from hosts whose name resolves to an IP address, and whose IP address resolves back to that name. Other hosts that hub.freebsd.org rejects mail from are those that are found in the Dialup-Users-List [see http://maps.vix.com for more details on DUL]. A way to solve this problem is to forward all mail to the mail exchanger of your ISP, as is the canonical way when sending mail over a dialup link. To accomplish this you can add the line define(`SMART_HOST', `mail.your-isp.net')dnl to your master-configuration file and regenerate your sendmail.cf from it. Then all mail will be first forwarded to mail.your-isp.net, and that host will have to deliver them to their final destination. The mail server for your ISP is not very likely to be on a list of dialup machines, since it's (supposed to be) always up. Therefore, freebsd.org will not reject mail that it receives from that host. -- Giorgos Keramidas, For my public pgp2 key: finger -l keramida@diogenis.ceid.upatras.gr To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
