We just upgraded from CF7 to CF8 (8.0.1). We run Enterprise Edition across 2 servers with 4 CF instances on each.
In the course of the upgrade we backed up our CF7 settings to CAR files and then deployed them on the new CF8 instance so all our CF Admin settings are identical to the previous version.
No significant code changes have been made.
However, many of our scripts that use CFMail, both on our sites and in scheduled tasks, have begun sending their messages multiple times. The same message gets emailed 2, 3, 4 times or more.
I found this email string on a Google search of someone with the exact same issue. I've tried to contact him to see if it was resolved but have had no success:
http://www.mail-archive.co
More details:
-The ColdFusion logs indicate that the mail was only sent once.
- Looking at our mail server the messages do, indeed, arrive multiple times. This eliminates the possiblility of an email server or Outlook/email client problem.
- CF Admin settings: Spool messages to disk, spool interval: 15s, Delivery threads: 10
So, it appears CF thinks it is only sending once. That tells me perhaps the underlying Java may be sending multiple messages AFTER CF has written its logs...
I've applied the latest Cumulative hotfix. No help.

Found my own answer. In Jrun4, when starting the CF instances, some of the "Start" buttons had been clicked more than once causing more than one instance of the individual CF servers to start. So, when CF spooled mail to the hard drive, multiple underlying Jrun servers then went about sending the messages...resulting in multiple email message deliveries.
We run CF Enterprise and use Jrun 4 to create and manage 4 separate instances of CF on each server. We saw the extra instances running in Windows Task Manager of all places. In our setup, each instance in the Task Manager shows as a Jrun.exe process and normally there are 5 running: one each for 4 CF instances and one for Jrun itself.
Hope this helps.

CFMAIL might be getting triggered at both of your instance and that can do this.
