Episode 10.4 (Hugel) introduced the Mailing System, which allows players to send mail via your Friends list (as long as you have one friend), your Party list (as long as you are in a party), or through the Mailbox. Your mail is accessed via a Mailbox NPC in all major towns. Players must pay 130 Zeny each time they wish to open the mailbox. Mail will be deleted automatically once your mailbox is full, starting with the oldest messages. The mailbox holds up to 30 messages at any given time. Any mail you have opened must be taken care of in order to see next one. Mail cannot be sent if it contains foul language and cannot be sent to characters on the same account.
