Problem with mail in CF8

Hi All.

I have a problem with a CF8 install that a client has in that I cannot connect to a SMTP server to send mail through it. Description as below.

Setup:

Tomcat 6

CF8.0.1

Java 1.6.0_24

Windows Server 2008 R2

Problems:

• In CFAdmin I cannot verify that the email settings are correct, even though they are. I tested the settings using telnet and sent mail fine.
• Attempting to actually send an email with the correct settings - through cfmail attributes - gave the following error:

"Error","scheduler-1","01/31/14","17:03:52",,"smtp"

javax.mail.NoSuchProviderException: smtp

          at javax.mail.Session.getService(Session.java:611)

          at coldfusion.scheduling.ThreadPool.run(ThreadPool.java:201)

          at coldfusion.scheduling.WorkerThread.run(WorkerThread.java:71)

Last time I had this problem on the server I fixed it by following the instructions here: http://www.coldfusionmuse.com/index.cfm/2012/5/4/Able-Commerce-5-on-CF--Email-Problem but this time it hasn't worked! Sadly I don't have a backup from when I fixed it last as this is our staging server on amazon which got deleted while I was on holiday and I had to rebuild it from our live server.

Any help would be greatly appreciated as I'm approaching insanity on this one!!

Thanks, Simeon.
