I have a new clean install of ISP config using the Ubuntu "Breezy" How To. Everything seems to be working fine. I have setup two email users. I can receive email. I have a "Hotmail" account and when I send a test message to my hotmail account it is not delivered. When I look at the mail.log file I find a listing that states the following: Name service error for name hotmail.com Type MX: Host Not Found (try again). It has been trying for 16 hours without success. When I "ping" hotmail.com it resolves to an IP address of 64.4.32.7 but there are no responses. I do believe the microsoft has a policy of blocking all icmp echo responses. I did a "whois" search on that ip address and it is registered to MSHOTMAIL. Why can't my server resolve hotmail.com Thanks in advance Chuck Rudolphy
resolv.conf The contents were: search ccrudolphy.net (my domain name) nameserver 192.168.4.1 (my gateway router) I have changed the file to: search ccrudolphy.net nameserver 192.168.4.4 (local DNS server) nameserver 24.93.40.72 (ISP DNS server) nameserver 24.93.40.77 (ISP DNS server) I restarted Postfix with /etc/init.d/postfix restart In looking at the mail.log file it appeared that Postfix was trying to resend the email about once every 90 minutes or so. Should be ready to resend in about another 30 minutes. We will see? Thanks - Chuck
You can flush the mail queue immediately by running Code: postsuper -r ALL as root (yes, ALL must be in capital letters...).
Resolv.conf That fixed it. I should have known what the problem was, but I am so used to working with a GUI (Windows, KDE, etc.) that working from the CLI only, threw me off. Your help got me looking in the right place. Once I saw what was happening I knew how to change it. Thanks loads foryour help. Chuck
