Actually I do. It affects to a sender of Newsletters (regular). I was shure the counter of maxSMTPipConnects resets during transferring a message, but it doesn´t. If I check the logfiles für "limiting connections" I see this feature as an exellent criterium. The sender sends one mail after the other - his server always makes max. one connection per destination-host. But the mails are small and the connection is fast so it surpasses the defined limit in the 90 seconds easy. > It seems this is a qmail habit - I've no experience of > qmail, can anyone confirm?

I set maxSMTPipConnects now to 16 (wich is the number of NL-reciepients from that server) and can see in the logfiles, that it is still working to catch spam-hammerer - they would reach any limit I bet. I was scared to smaller the rolling window because 90 seconds "feels" like a good choice. What I would like to know is what the ASSP-Answer is, if "maxSMTPipSessions" is surpassed - a 451 or 450 or 55x - which results the reaction of a sending host is retrying or aborting. If it is a "friendly" 451 it could make relly sense to set it to "1". laters Christian ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Assp-user mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/assp-user
