don't waste your credits on storage boxes or additional slots.. you can mail yourself anything you want.. right now I have a mail box with thousands of ingots.. I just leave them their as unread mail until I want to use them.

You can write the subject line as what items are included to make sorting them easier

Can anybody confirm?

yes, this is common knowledge. Not only that this works in just about every mmo.

You can also mail across faction. Though people should know this.
