Email Address
This is the most common type of entry you will add to your whitelist. For example, if you have a friend with the email address friend@myfriend.com then you merely add friend@myfriend.com to your whitelist and any email sent from friend@myfriend.com will be delivered to your mailbox.
Domain
A domain allows you to whitelist a large group of email addresses from the same domain. For example, say you do business with the ACME company and they have the domain acme.com. You receive email from several different people at the company, such as joe@acme.com and jane@acme.com. Instead of having to add every email address from acme.com that you could possibly receive email from, you can just add the domain acme.com to your whitelist, which would allow you to receive email from anyone using an acme.com email address.
To add a domain to your whitelist, you merely add the domain name (acme.com in our example above) to your whitelist and any email sent from an acme.com address will be delivered to your mailbox.
One of the disadvantages of using a domain in your whitelist is that it can increase the possibility of spam slipping through your whitelist. For example, some domains are very popular with spammers (such as yahoo.com). If you happen to add a domain to your whitelist that is used by spammers, your chances of receiving spam will increase because you are letting all messages from that domain through.
Please be aware that any domain (or email address) can be used by spammers to send out spam. Due to the inherent weaknesses of the protocols used to send email over the Internet, there is no reliable way to verify a sender's email address at this time. We recommend that you do not whitelist domains of large ISPs or businesses because they are often the targets of spammers.
Normally, when you add an email address or domain to your whitelist, it is checked against the sender (From:) address. For example, if you whitelist friend@myfriend.com than any email with the From: address friend@myfriend.com will be delivered to your mailbox.
There are situations in which this normal behavior is not practical and you will want to check against the To: address instead. Most likely this will occur if you are subscribed to a mailing list. Generally, when you receive a message from a mailing list, the From: address is the email address of the person who originally sent the message to the list. Thus, you would have to add every subscriber to the mailing list to your whitelist in order to receive your mailing list messages.
Fortunately, the To: address on your mailing list messages will be the same for each list message you receive. For example, if you are subscribed to the mailing list list@mailing.com, then every message from the list might have the same To: address of list-subscribers@mailing.com. Thus, you need only to add the To: address of your mailing list to your whitelist in order to receive your list messages.
To add the To: address to your whitelist, merely add To: to the beginning of the email address. For example, if the To: address for your mailing list is list-subscribers@mailing.com, then add the following to your whitelist:
To:list-subscribers@mailing.com
The To: in front of the email address tells your whitelist to check the address against the To: address instead of the From: address.
