We have recently begun experiencing a problem sending messages via cfmail. 
We're not sure
 exactly when this started occurring. Our users just brought it to our 
attention, but the
 ColdFusion logs indicate this problem has been going on for a few weeks.

 We have several ColdFusion 7 applications on our intranet that, among other 
things, generate notifications
 to our users via the cfmail tag. Some of our applications, all in-house 
developed, have been running
 successfully for years. And all applications exhibit this aberrant behavior.

 For some as yet unexplained reason, ColdFusion has started randomly and 
 generating multiple email messages to users. Sometimes a user will correctly 
receive a
 single message, sometimes multiple. Multiple, meaning 2 or 3. There is no 
looping involved when creating
 the message, no attachments, and the message is always addressed to a single 

 I don't believe it to be a CF scripting problem. As I was watching what was 
 on the server I was capturing a copy of the mail spool file before ColdFusion 
grabbed it and compared that with what was reported in the mailsent.log file. 
Sure enough, sometimes a single spool file would result in
 multiple messages, and sometimes only a single message--to the exact same 
person. But this doesn't 
 happen to everyone.

 I don't see anything wrong with the contents of the spool file. A spool file 
that generates a single
 message looks exactly the same as one that results on multiple messages--to 
the same user--and it appears to happen randomly.

 I can't be the only one in the world to experience this.
