Okay, but what's the issue? Describe it.

a) Can't send mail crossfaction (unless they are heirlooms) - considering Damb is Horde, and Dambl is Alliance
b) Can't send mail across realms.
c) Make sure mail you're trying to send has the right receiver. Damb and Dambl might be auto-filled to wrong characters.
d) Some items can't be sent due to them being soulbound items (binds on pickup, enchantment made it so, quest rewards etc.)

Can you show screenshot of the item(s) in question? If you're still unsure of what's the issue, or if it's not 'resolved'.
