Just wondering if there are more Mohave Express mailboxes around the wasteland. I am on level 12, normal mode and have found 3 such boxes in Goodsprings, Primm and Novac. It is a very nice usage of time and space (especially weigh concerns) when you can mail items to where you are going to be in any quest. I try and 'not' use fast travel...so this option is good for me. Any help would be appreciated. Thanks in advance.

There are two more Mojave Express dropboxes in the wasteland. One in Freeside by the Mormon Fort and one inside the New Vegas Train Station.

You can actually send things with the Mojave Express boxes?

Yep. You drop your stuff in any Mojave Express dropbox, and you can send it to any other dropbox you've found.

Awesome! Nice feature Obsidian
