Setting of DNS
Contents
Primary DNS
Primary DNS-server. It can be given both by domain and by IP-address. Advanced Direct Remailer works with DNS-servers only via UDP protocol. The access time to DNS-servers, which the program uses by default, is 2-3 seconds for some users. Apply to your Internet provider for its DNS-server address, if you want to shorten this period till half a second. Windows can get this information automatically sometimes. And most of providers use this feature to guard user from superfluous settings. ADR tries to determine DNS settings by itself and show them in “Windows DNS Settings”. You can also determine DNS-servers addresses independently using IPCONFIG utility with key /ALL under Windows XP Also you can take DNS addresses from DNS servers list.
Secondary DNS
Secondary DNS-server, it can be empty. It can be given both by domain and by IP-address. It is used only if the primary DNS-server has not answered to the request positively.
Try to delivery by name
Direct delivery. For example, direct delivery to server gorlach.koenig.su for address alex@gorlach.koenig.su. Even if the direct delivery is set, it is used only when DNS-servers have not returned the addresses of mail servers. Using this option IS NOT RECOMMENDED.
Don’t use internal DNS cache
If you have two emails from one domain (e.g. a@hotmail.com and b@hotmail.com) in your mail list, then the program will retrieve addresses of mail servers for second email from its internal cache. You can turn off caching by checking this option.
Windows DNS Settings
Information in this window is updated every second automatically. Program tries to determine DNS settings of Windows by itself and show them in this window. If you have dial-up connection then establish the connection at first in order to ADR can determine DNS settings. You can also determine DNS-servers addresses independently using IPCONFIG utility with key /ALL under Windows NT, or using WINIPCFG utility under Windows 95 or Windows 98. They are utilities of operation system.
Auto update DNS settings
Automatically replace primary and secondary servers by system DNS, if they are found. Settings check and update happen every second. DNS settings not updated when program settings window is opened.
