Gmail claim (Slash Command)

Warning! Do not use this command. It is meant for internal purposes and can break global chat for your character.

From the Issue 8 Page 1 Patch Notes:

* Remove /emailsend, /emailsendattachment, /gmailclaim, and /gmailreturn slash commands. These commands were intended for internal use by the UI and correct usage depends on knowing internal character state that is not visible to the player. Incorrect usage can leave the player's mailbox in a corrupt state that renders it unusable without manual administrator intervention to fix the database records.

This command is used internally to claim items from in-game email. It is not intended to be used by players and has serious consequences.
