Hi,

We have a single user mailbox receiving thousands of spam emails in the last hour. How can we stop this? We checked a couple of headers and the sender is from multiple ip adresses.

You can either try to find a common thing around all those messages and block them, or create a separate, more restrictive antispam policy and assign it to that user.
