Claudia, I've learned the hard way -- insist that subscribers send you at least two headers off the messages they're complaining about. Otherwise, there's no way to tell what's going on. There are lots of possibilities and it's hard to track them down without the mail headers. In your case, I'd ask the subscriber to forward to you the entire message, both copies received, including the headers. Valorie King TAGFAM [log in to unmask]
