Some prisons restrict the delivery of mail sent by a 3rd party. Mail sent using your personal or home address should never be flagged as coming from a 3rd party, however, if you use Jmail's mailing address as your return address, your mail could be rejected due to 3rd party mail violations. Please confirm that the prison/jail you are sending mail to does not have any 3rd party mail restrictions. If so, please use your personal address instead for those letters to avoid your mail potentially being rejected. Jmail is not responsible for rejected mail due to 3rd party violations as it is your responsibility to follow the rules of the prison to which you are sending correspondence.
