Possible to mailing items between own characters?

Is there a way to mail items or gil between my characters ?
I f i won do that i get the message that im not frinds with my character i wish to mail to ? :confused:

Housing will eliminate any need for this. As it sits right now, you need to rely on the FC Vault to move between characters.

Sadly the best way to do this right now is to use a free company storage.. It's very annoying
