Guest: I responded to your e-mail earlier with the same suggestion Hal just provided you, and got the following message, that seems to be the source of your problem:
.net 007: This e-mail message was undeliverable due to the
.net 012: The recipient(s) account is temporarily over quota.
1. Contact the recipient by alternate means to inform them that their
mailbox is full.
2. Ask the recipient to pop/delete their e-mail before additional e-mail
can be received.
