Yes, but whatever you do DO NOT use the query attribute of CFMAIL. You will flood CF and the your mail server, probably crashing both and losing your batch of emails. ColdFusion is a little too efficient at producing the emails like this. If you're using CF to spool the mails to your mail server, you should look at introducing code that sends a number of emails, checks to see how many emails are in the spool folder and put a wait in until the queue goes down and then send another batch of emails. You'll hear tales of people sending upto 100,000 emails at one go with no problems, but then someone else will lose/bouncing 1 in 5 emails when sending 10,000 emails. CFMAIL is very useful, but it leaks memory like a sieve. So sending this number of emails using CFMAIL will probably require a restart of CF after its completed to free up the lost memory. Your best bet is to integrate directly with your mail server by writing the emails the mail servers spool or looking at infusion Mail Server, which being CF-based is very easy to integrate into (currently runs the houseof fusion mailing lists 1mil+ emails daily) http://www.coolfusion.com/products/ims/index.cfm Hope this helps.
