SNDEMAIL problem

I'm using the Sndemail Utility that was downloaded from the
IseriesNetwork Site.  We have been using this utility for about  1.5
years now.  However, during the last 4 or 5 months we have started
encountering  'Phantom' Emails.  This is happening for only 1 report,
and is repeating in an inconsistent pattern.  
 
We have a report that runs from the job scheduler every night that
created a PDF document on the IFS, deletes the spool file and then
emails the document to 4 different people.  
 
What we have encountered is that this report is mysteriously being
emailed to other users weeks after the original email was sent.  
 
The one constant i have been able to find is that the orignal report we
have problems with seems to be always from Sunday.  Below are some
examples of dates of reports and when the phantom email was received. 
 
original            Phantom
12-01-02        01-01-03
02-16-03        03-14-03
12-22-02        01-13-03
 
 
Below is the header of the email that was received by a user(not Ed

Someone has advised me to look in the QTCPTMM folder for anything
hanging out there.  I have been monitoring this, but haven't seen
anything that would indicated this is was is happening.  

 

Does anyone have any clues on what might be causing this,  how to track
it.  

I'm at a loss on how to solve this.  

 

Thanks

 

Mike
