I've wrote a program that integrates with the smtpd32.acc file.  Scott 
is right though that their is some 'standard' format to the beginning 
and to the end of the file.  What I've been able to discover is that the 
static contents of the file, before any addition of data, seems to be 
consistent with the other *.acc files.  The data at the end of the file 
I would think needs to remain constant probably as an end of file marker 
to the calling routine within IMail.  The static data at the beginning 
of the file is a mystery to me.  I originally thought it was necessary 
for the calling function within imail to work correctly - and it still 
might be.  Digging a little deeper I suspect maybe it was being used as 
a pointer to how many records are maintained in the file.  It could also 
just be that "satic" data for the imail program to work correctly.

If someone could send me their smtpd32.acc file I could better compare 
the files to ascertain if they are similar or dissimilar.
