| AS3 Mailbox / AS3 Mailbox: Certificates Tab | |
By default, the certificates you configured on the Certificates tab of the Local Listener panel will be the certificates used to sign messages sent to your trading partner and decrypt messages received from your trading partner. See Configuring certificates for Local Listener.
Use Override Local Listener Certificates to select alternate certificates for signing and decrypting messages with this particular trading partner. If you do override the default the certificates, don't forget to export and exchange these alternate certificates with your trading partner.
