Synchonize option is available for any email provider. |
WHITE is an abbreviation for "DNS whitelist". It is a list of IP addresses that some people may want to treat more favourably. nsZones provides a Whitelist of known legitimate email servers to reduce the chances of false positives while spam filtering.
The purpose of a White list is to specify elements whose inclusion in an e-mail guarantee it will pass the filter and be delivered.
In this list, mail servers of Internet service providers (ISP) and known email providers (Google, Hotmail, Yahoo) and others are included. Also payment and software solutions, hosting and domain providers, other trusted services are in this list.
Every IP that is not known to be a source of abuse itself can be registered at white.rbl-dns.com. Registration is with one time fee of 30 Euro.
Purpose of white.rbl-dns.com is to improve deliverability of legit emails send by registered IP's. Therfore registered IP's are excluded from blocklists as spam.rbl-dns.com, dul.rbl-dns.com and bl.rbl-dns.com.
To prevent that abusers will deliberatley register their IP's with white.rbl-dns.com we will drop every registered IP from the whitelist immediatley as soon as any kind of abuse is originating from it.
You can check if your IP address is listed, using our white list database check.
white.rbl-dns.com
If you use any of the Black Lists
bl.rbl-dns.com
spam.rbl-dns.com
dul.rbl-dns.com
you do not need to check also the White List
white.rbl-dns.com
The White list is included in the Black List DNS system.
In general, DNSWL queries are structured by the inverse IP address as a subdomain of the DNSWL zone. For example, to check that the general DNSWL test address of 1.2.3.4 is listed in WHITE, query 4.3.2.1.white.rbl-dns.com with any NS lookup tool such as...
4.3.2.1.white.rbl-dns.com
You will receive an address 127.0.0.5
