Whitelist
NOTE
Whitelist affects only Anti-Spam filters and not email security and content filtering
The Whitelist contains lists of criteria that identify legitimate email. Emails that match these criteria are not scanned by anti-spam filters and are always delivered to the recipient. Emails can be whitelisted using the following criteria:
- Sender’s email address, email domain or IP address
- Senders to whom an email was previously sent (Auto-whitelist)
- Recipient (exclude local email addresses from having emails filtered)
- Keywords in email body or subject
The whitelist and Auto Whitelist features are enabled by default.
Important notes
Using the Auto Whitelist feature is highly recommended since this eliminates a high percentage of false positives.
In Keyword Whitelist it is recommended to add terms that spammers do not use and terms that relate to your nature of business, for example your product names. Entering too many keywords increases the possibility of emails not filtered by GFI MailEssentials and delivered to users’ mailboxes.
Whitelisting an internal user defeats the purpose of the Anti-Spoofing filter. For more information refer to Anti-Spoofing.
