Depending on their current level, your Fish, Wood, or Iron Storage will have a maximum quantity they can hold. If your storage is full, certain actions may still provide you with the excess Fish, Wood, or Iron, placing it in your mailbox.

The following actions will send excess resources to your mailbox:

You will not receive excess resources from any other activities, such as:
