Using the whitelist, you can define the senders from whom you want to receive email. If you add an email address or domain (e.g. 1and1.com) to the whitelist, email from the address or domain are automatically saved to the Inbox folder. Email from senders on your whitelist are not checked for spam.
Using the blacklist, you can block senders of unsolicited email. If you add an email address or domain (e.g. evildomain.com) to the blacklist, email from the address or domain are automatically moved to the Spam folder.
If you add an email address or domain to your whitelist, corresponding entries are removed from your blacklist automatically. If you enter an email address or domain in your blacklist, corresponding entries are removed from your whitelist automatically.
You can add up to 5,000 entries to your whitelist.
If you want to enter domains in your whitelist or blacklist, write them as follows: domain.com.
To enter newsletter senders in your whitelist or blacklist, we recommend that you enter the entire domain (e.g. gooddomain.com or evildomain.com). The sender address often changes every time a newsletter is sent. If you enter a domain (e.g. gooddomain.com or evildomain.com), the corresponding individual email addresses (e.g. "firstname.lastname@example.org" or "email@example.com") are removed automatically.
If your email are classified incorrectly, remember that your filter rules are processed before your whitelist and blacklist. Examples:
The Not Spam entries in your personal spam filter are also processed before your blacklist. Example:
