This should free up a lot of mailbox server resources simply and quickly. Plus with the MX's as anti-abuse gateways, you'd probably reject at least 20% to 90% of incoming mail as spam. btw, postfix has been tested faster than qmail for local deliveries. :)) But I wouldn't horses now, you have archictectural improvements that will yield more. >I am thinking on a dual xeon DELL poweredge 6600 with 6GB ram and two 73Gb >SCSI I guess you mean two 73 gb in RAID1 ? or are you running 1 million mailboxes without mirrored disks? You are probably suffering primarily from disk congestion. No matter what MTA, you should have your mailqueue, mailboxes and logging on different drives and/or controllers. Maybe send the logging to a separate log server to remove that disk i/o from the local disks.
