Whitelist / Blacklist an e-mail address

PolarisMail Our system automatically whitelists e-mail addresses that you communicate with, for your entire domain. For example, within your domain hosted with PolarisMail us, you have two users: joe@domain.com and amy@domain.com. If joe e-mails mary@hotmail.com , mary@hotmail.com will become whitelisted for both joe and amy. If mary@hotmail.com decides to write to amy@domain.com or joe@domain.com, her e-mail will get through without being filtered. For more details on this, please see our page about whitelist / blacklist on domain level.
