Peter:
 
I really don't know the cause. It seems that our LISTSERV is running
smoothly: other mail is being distributed correctly.
Our MAILER also runs OK, so I can help only by providing aditional
data about the problem.
 
Below you will find the (partial) console log.  It seems that the
file received  wasn't the one you (originally) sent to [log in to unmask]
 
If any of you discovers the cause of the problem please let me know.
Best regards,  Miguel.
