Yes, of course that is on other machines. If you do up to 1000 mails/s, it's more than one machine usually :-) > I set my system (Postfix) > for 20 concurrent instances and passed off the final message > insertion to a separate machine and processed over 70,000 queued > messages in less than an hour on a single AMD 4200+ with 2GB RAM and > a SATAII disk system.

But I'd need to know the dbmail insertions/s, not the postfix filtering speed. Anyway, thanks for your help! What system/hardware is your dbmail server? That's the critical point for me: the spam filters can be several parallel machines without a problem, but dbmail can only run on One Big Iron, that makes me headache. mfg zmi -- // Michael Monnerie, Ing.BSc ----- http://it-management.at // Tel: 0676/846 914 666 .network.your.ideas. // PGP Key: "curl -s http://zmi.at/zmi.asc | gpg --import" // Fingerprint: AC19 F9D5 36ED CD8A EF38 500E CE14 91F7 1C12 09B4 // Keyserver: www.keyserver.net Key-ID: 1C1209B4
