What I do is have two ip is the mail server with qpsmtpd lissening on one & qmail-smtpd on the other. Thus buy DNS mx what ip gets mail. Thus buy domain wether to filter or not. > 5.

I would recomend not turning down the queuelifetime too much five days may be a long time but there a multiple resonse for it. Just watch your Q some time. It isn't uncommen for a message to sit for hours or days because some exchange server somewhere needs to be rebooted. tmb
