blocking

I have a client with an Exchange server on which there are quite a few mailboxes.

One mailbox in particular is causing some problems. When an email from a certain address arrives, it appears to prevent Exchange from successfully delivering the email to the Outlook Express inbox. The address in question is from an account with Bigpond, or at least I think it is, I didn't check to see if it was spoofed (only just occurred to me.)

Any emails in the queue before the suspect email are delivered, then Express times out. When send/recv is retried those emails are re-received and the process times out again.

The process I have for fixing this is to log in to the sever, load Outlook, open the recipients inbox, and delete the suspect email. Then retrying the send/recv on Express successfully retrieves all the messages (except for the deleted message.)

This solves the immediate problem, but this has happened several times now, and each time requires the process above to correct it.

What I am wondering is if there is anything I can do to fix this permanently. It seems to me that Exchange should reject a dud email message rather than getting stuck. Does anyone know what could be causing this, and how I can fix it?
