Which customers will complain? Consider the case where you have customer A and ex-customer B, and you still have ex-customer B zones loaded in your master dns servers. The rest of the world properly sees the (new) zone content for ex-customer B. But when your existing customer A tries to send mail to ex-customer B, it may go to the wrong place or bounce. And that will only happen for your *other* customers. B thinks everything is ok, since they can receive mail from gmail, etc. To properly serve your customers like A, you need to purge B's zones soon after they move, whether they notify you or not. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (GNU/Linux) iEYEAREKAAYFAleenRYACgkQL6j7milTFsGq3gCdGXY2Ge1QCQrHqDNAeLswpnxH IgkAniYF2K5whptZz7aetH4GTbu4A78z =m/gF -----END PGP SIGNATURE----- _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
