You can create an exception list to the general spamBlocker actions that is based on the sender’s or recipient's address. For example, if you want to allow a newsletter that spamBlocker identifies as Bulk email, you can add that sender to the exception list and use the Allow action regardless of the spamBlocker category the sender is assigned to. Or, if you want to apply a tag to a sender that spamBlocker designates as safe, you can add that to the exceptions list as well.
Make sure you use the sender’s actual address that is listed in the “Mail-From” field in the email message header, which may not match the address in the “From:” field that you see at the top of the email message. To get the actual address for an exception, get the full email message header (from Microsoft Outlook, with the message open, select View > Options and look in the Internet headers box). The addresses of the sender and recipient are in these lines:
X-WatchGuard-Mail-From: X-WatchGuard-Mail-Recipients:
Use care when you add wildcards to an exception. Spammers can spoof header information. The more specific the addresses in your exception list, the more difficult it will be to spoof them.
