I do something similar: my SA plugin runs the SQL query against a view of my mail archive, which is in a PostgreSQL database. Martin

If you want to strictly test for both remote_email@remotedomain and mail@mydomain, I'm afraid you need a custom plugin for it.
Re: a simplified, home-made txRep?
Thank you to both for your answers. Yes, I meant TxRep. My text file is in this format: mail@mydomain,remote_email@remotedomain My goal is to lower the score of messages coming from remote_email@remotedomain and addressed to mail@mydomain. Of course, each user can have a different list of addresses and as I said, there are about 610.000 lines in the file. There are 360.000 unique remote_emails in the file...

Did you actually mean TxRep? IIRC there's another plugin that learns addresses from outgoing mail, but TxRep doesn't require it. > You can dump them in enlist_addrlist format to .cf file > > enlist_addrlist (KNOWN_FROM) f...@bar.net > enlist_addrlist (KNOWN_FROM) b...@another.com > ... > header KNOWN_FROM eval:check_from_in_list('KNOWN_FROM') > score KNOWN_FROM -1 > > If you have thousands of entries, it might slow down things > marginally (the list is fully iterated for finding matches, but > shouldn't be a problem unless you have million). > > Of course From header could be forged etc, currently there's no > function to check only envelope sender which might be safer. The envelope is not much safer, but you can do this: meta KNOWN_FROM_AUTH KNOWN_FROM && (DKIM_VALID_AU || (SPF_PASS || __RP_MATCHES_RCVD) && !HEADER_FROM_DIFFERENT_DOMAINS)

Of course From header could be forged etc, currently there's no function to check only envelope sender which might be safer. If you have Postfix, I wrote similar daemon to do this dynamically: https://mailfud.org/postpals/
a simplified, home-made txRep?
In a 28mb, 610K lines text file, I have a list of all my users and the email addresses they *sent* a mail at least once. I'd like to use the info to add a -1 point when a mail is received from one of these addresses. Unfortunately, at the moment, outgoing mail is not processed by spamassassin so txRep is not good... any idea? Thank you Francesco
