TxRep was designed as an enhanced replacement of the
AutoWhiteList AutoWhitelist plugin

TxRep, just like AWL, tracks scores of messages previously received, and adjusts the current message score, either by boosting messages from senders who send ham or penalizing senders who have sent spam previously. This not only treats some senders as if they were whitelisted but also treats spammers as if they were blacklisted. Each message from a particular sender adjusts the historical total score which can change them from a spammer if they send non-spam messages. Senders who are considered non-spammers can become treated as spammers if they send messages which appear to be spam. Simpler told TxRep is a score averaging system. It keeps track of the historical average of a sender, and pushes any subsequent mail towards that average.

It means that if your server is set up to use IMAP folders, webmail, or other tools for training SpamAssassin, the TxRep reputation will be adjusted at senders of all the trained messages anytime you use it. More details about the algorithm are available in TxRep POD.

Additionally, you can also enable the txrep_autolearn option. In such case, when the message scores trigger SpamAssassin's , 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, . TxRep will add or subtract additional points to the stored reputation in such case. To activate this feature, you need to enable the option txrep_autolearn. Do not activate the auto-learn option before SpamAssassin is well tuned, and before it sorts spam and ham correctly. With poorly trained SpamAssassin, the auto-learn function of TxRep would boost also all false results. Add the autolearn value to the email headers (i.e. "add_header all Status ... autolearn=AUTOLEARN" in local.cf), and activate the txrep_autolearn option only after you verified that SA triggers the autolearn process only in the cases when you clearly want to boost the sender's reputation (in one or the other way).

How do I whitelist/blacklist someone?
