Outgoing Mail message sent multiple times

Searching your archive, I noticed several people mentioning this problem, 
without a solution indicated.  I also had a problem with mails being sent 
multiple times, and believe I have isolated the problem.

I access Neo-Mail from my Control Panel.  I press a hyperlink/image that says 
"Neo-Mail", and then get into the program after providing the appropriate 
login information.

After I send a mail message, the only obvious navigational option to get back 
to my Control Panel is to press the Back button on my browser to back all the 
way out of NeoMail.  I believe that is what generates duplicate sent 
messages; pressing Back after sending a mail.  I have since gotten in the 
habit of manually changing the URL in my browser's address bar after sending 
mail.  Needless to say, that isn't a particularly user-friendly solution.  I 
suggest you recommend to sys-admins that they configure the NeoMail hyperlink 
on their control panel to open the program in a new browser window.  That 
would likely minimize/eliminate this problem, as users could simply close the 
window when they are done.
