As you see, MAIL FROM (SMTP protocol) and From (DATA) are different, and Amavis+SA+Postfix is acceptiont this. Is this a SA task or Amavis or Postfix,
Hi Luis, I am running a custom filter in qmail to do exactly that. To be honest, it took me about 3 months to get that working right. Basically the rules are: a) If the To address matches one of my possible email addresses (the filter is applied after collecting mails from a few pop mailboxes), and I am the only recipient, let the mail through b) if the (mailfrom or from) sender is in a whitelist (populated from mailing list senders, and very few colleagues that send BCC), let the mail through c) If I do not appear in To or Cc at all, quarantine the mail d) If there are more than 3 or so recipients (in particular from @t-online.de, which is a big ISP for private users), and not at least one of them also appears in that whitelist, quarantine e) Potential addition: detect display names that do not match those you use for sending I still look at a quarantine summary - some mailing list could have changed or so, or maybe there is an annual mailing list reminder that does not match the whitelist entry As you can see, this is solution for a single recipient, not for a mailserver, and as such it could perhaps be done in a procmail recipe.
