From Legacy Wiki
The Post Office, located in Sector 2, is where you can access your Legacy 'email'.
Here, you can:
- read messages that other players or staff has sent you
- write new messages to other players
- delete your messages one-by-one, delete all your read messages, or delete ALL your messages, including unread messages.
Your Inbox can hold 50 messages at one time, and players cannot send messages to you after you have reached 20 messages. To solve this, simply delete some messages.
In addition, you can select your inbox privacy options. The options are:
- Allow all to message you
- Block those who are in the below list
- Allow only those who are in the below list
- Block all
Account names that you type in the list are not case-sensitive.
