Higher number of deliveries

Hi there,   IM very sorry for the long mail that I have sent. But Just elaborating the problem as I could not understand what and where was the glitch in my config.   We have a database of 100,000 mails and we will be sending personalized mails to each user automatically. We use redhat 6.2 ( extfs, kernel 2.2.14 ) and qmail for mailing.   Before mentioning the problem the config parameters that I have used in qmail and system config are system config -------------- dell poweredge server with 1GB RAM and scsi disks with 12000 rpm, dual CPU. redhat 6.2, kernel 2.2.14, extfs. Network bandwidth = 22Mbps   qmail config -------------- concurrencyremote = 400 queuelifetime = 345600 timeoutremote = 600 timeoutsmtpd = 600   and all the others are default parameters.   The problem is that, when I tried sending  4700 mails ( to different domains ..... say like yahoo, hotmail, rediff, etc and not a single user in my domain ), it took one whole day to send all the mails.. qmail-inject placed mails in the queue at a speed of 70 - 90 mails in a second. But, if the logs are checked, it took one whole day to finish sending all the mails   Was I wrong anywhere or missed any configuration ???????   What should I do to send say a million mails in a day ?   Thanks & Regards, Rajesh, tech solutions, [EMAIL PROTECTED], Intercept Consulting - INDIA.
