John, I have completed a series of contracts with permission email marketing companies in SFL. All of which I used iMS POST as proof of concept configuration. The maximum emails sent per machine that I achieved was 300k per hour. (After many emails and phone calls with Howie.) This is arround 3 times as much as Linux machines setup to do the same. The intial coding was done at BVG over a one month period. They are sending around 30 million emails per day. I would be happy to send the details of the configuration, and how to calculate bandwidth usage. Remember it is not possible to get a golf ball through a straw!

I configured the RAMDisk to hold the POST spool directory. While I did see a slight performance increase for creating files with CFX_iMSMail, the net improvement in my overall sending speed was marginal. Also, after sending about 1 million emails my server locked-up with some odd memory related errors in the event log. I have removed the RAMDisk from my server. I have tried several approaches now to increase the rate at which iMS POST will send emails. No matter what I try, it seems like 23K-24K per hour is the limit. We would like to double this rate to around 50K/hour. Has anyone achieved this speed from a single server? If so, how? Note that we send unique emails that average about 15KB in size. We have no bandwidth restrictions. We have the full enterprise version (1024 threads). Thanks.
