IMPORTANT: White/Black lists do not affect in any way SMTP Rejects. To create SMTP whitelists see document: SMTP Override Checks Even though LibraCyber ESG has one of the most powerful Antispam engines, there can be many circumstances in which it is necessary to refer to a whitelist or a blacklist. It is therefore important to understand how to apply the right rule. The first thing to understand is how LibraCyber ESG works; keep in mind the following few points:
- LibraCyber ESG has a multi-layered spam engine. Each layer uses its own rules.
- White/Black Lists are not and never universal allow/disallow rules against intended senders/recipients
- White/Black Lists work only on the antispam checks: antivirus checks, attachment policies, SMTP checks, and MCP rules are not affected and are evaluated in any case with separate policies.
- In other simple words, White/Black Lists can operate at the spam score level only.
- No jolly chars are admitted, use the keyword default to match all recipients
That said if you need to create a white/black list, go to Admin Area->Content Analysis->White & Black Lists. The Whitelist and the Blacklist entries shown operate according to the privileges of the connected user. The Administrator can view all system entries, the Domain Administrator can only view those of the domain he belongs to, and the single user can only view his entries and those referring to his associated alias. See some examples: To accept all emails from the info@libra.it address, fill in the add form as follows:
To accept all email from domain libra.it, to recipient info@miodominio.it :
If the Check only Envelope option is selected then LibraCyber ESG will check the entry only against the envelope address and not against the header From. Leaving it unselected the check will be done against both. All of the above is also valid for the blacklist or the management of the undesired mail senders. ×NOTE: If a message belongs to both lists (white and black), the whitelist has priority and the message will be delivered. It’s possible to import existing Whitelists/Blacklists from a CSV text file. Select the White/black list, click the Import button and select the source text file, that has to be formatted as follows:
- One record per line
- From_Address, To_Address
Once you checked the file format proceed to import and all entries will be loaded.
