![]() ![]() (ex: mailer-daemon 194.158) This is intended to penalize spam claiming to be From you with forged headers. Senders who are considered non-spammers can become treated as spammers if they send messages which appear to be spam.Ī sender is identified using both their address and the most significant 2 octats of their IP address Each message from a particular sender adjusts the historical total score which can change them from a spammer if they send non-spam messages. This not only treats some senders as if they were whitelisted but also treats spammers as if they were blacklisted. Tracks scores from messages previously received and adjusts the message score, either by boosting messages from senders who send ham or penalizing senders who have sent spam previously. The new plugin enhances the functionality of AWL, and works around some of its shortcomings. In your ~/.In March 2014 (rev 1579980), SpamAssassin introduced the TxRep plugin. You can also use both methods simultaneously. 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). To activate this feature, install the plugin, and enable the option txrep_whitelist_out. When parsing outbound email by SpamAssassin, you can automatically whitelist all recipients of the outgoing messages with the help of the TxRep plugin. Automatically whitelisting people you've emailed 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). Add the autolearn value to the email headers (i.e. With poorly trained SpamAssassin, the auto-learn function of TxRep would boost also all false results. Do not activate the auto-learn option before SpamAssassin is well tuned, and before it sorts spam and ham correctly. To activate this feature, you need to enable the option txrep_autolearn. 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.Īdditionally, 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 also allows the whitelisting and blacklisting of senders through the sa-learn tool. 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. ![]() If you want to whitelist, you should use the directions above.Īlternatively, there is also the AutoWhiteList successor - the TxRep Sender Reputation plugin. ![]() 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. ![]() What is AutoWhitelist?Īnother feature of SpamAssassin is "auto-whitelist". The whitelisting and blacklisting with TxRep is documented in details on its Wiki and POD pages. 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. 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. More info on whitelist_from, whitelist_from_rcvd, and blacklist_from is on the web or can be accessed from your local man pages by typing perldoc Mail::SpamAssassin::Conf. If the sender is at all well known (such as a mailing list), you should use whitelist_from_rcvd instead so that a spammer can't forge their mail to look like it's from the whitelisted address. Whitelist_from manually blacklist, use blacklist_from to add an address to your blacklist. ![]()
