Yes, I find it still useful, but I don't use it as a primary tool ever since postscreen has landed. Actually I was very happy to send it back into line, because it kills one of the most attractive features in email: instant communication. Nowadays we use it in rspamd, where it works as "dynamic greylisting" addon. Whenever a certain threshold has been reached rspamd sends the client off to greylisting. Any mail that stays below that threshold will not be subject to greylisting. I like that conditional behaviour better. It adds delay to email delivery only when in doubt. p@rick -- [*] sys4 AG https://sys4.de, +49 (89) 30 90 46 64 Schleißheimer Straße 26/MG,80333 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer, Wolfgang Stief Aufsichtsratsvorsitzender: Florian Kirstein
