Some good, free web-based tools are available to put a friendly user interface on whitelists (and blacklists) and allow users to edit their own. See WebUserInterfaces.

With the AutoWhitelist and TxRep plugins, besides their automated function, you can whitelist and blacklist email addresses, or (in the case of TxRep) also domain names, IP addresses, or NetBIOS/HELO names, with the command line options --add-addr-to-whitelist and --add-addr-to-blacklist of the main spamassassin script. The whitelisting and blacklisting with TxRep is documented in details on its Wiki and POD pages.

What is AutoWhitelist?

Another feature of spamassassin SpamAssassin is "auto-whitelist". But the name is a misnomer. The AutoWhitelist is designed as an automatic score averaging system, and is just as likely to penalize or blacklist an address as it is to benefit or whitelist it. If you want to whitelist, you should use the directions above.

Alternatively, there is also the AutoWhiteList successor - the TxRep Sender Reputation plugin. It whitelists and blacklists automatically and manually not only email addresses, but also senders' domain names, IP addresses, and NetBIOS/HELO names in the combination with IP blocks, DKIM signatures, and SPF passes. TxRep also allows the whitelisting and blacklisting of senders through the sa-learn tool. It happens automatically when training spam/ham to Bayes - depending on your configuration, it can be done by feeding the sa-learn tool individual messages, or entire mailboxes and folders manually on the command line, by user input in webmail software, through a cronjob from IMAP folders, or in other similar ways.

Additionally, TxRep, in similar way to the Bayes plugin, can boost the automated whitelisting/blacklisting at the scan time, when the score of the message triggers the auto-learn process. To activate this feature, you need to enable the option txrep_autolearn

Automatically whitelisting people you've emailed

When parsing outbound email by SpamAssassin, you can automatically whitelist all recipients of the outgoing messages with the help of the TxRep plugin. To activate this feature, install the plugin, and enable the option txrep_whitelist_out.

When not using TxRep, or not parsing outgoing email by SpamAssassin, you could use the following method to extract a unique list of e-mail addresses from your 'Sent' folder (in mbox format), you could use something like this:. You can also use both methods simultaneously.

In your ~/.spamassassin/user_prefs file, put this in:
