Re: Request: Please sign this list's messages via DKIM or SPF

Zitat von Binarus via Info-cyrus : Combine SPF / DKIM with domain blacklisting, and then you *have* an efficient spam fighting tool. As stated the spam actually reaching our inboxes after around 90% cutoff is valid DKIM/SPF signed as it is mostly from
