I am getting the following error when trying to schedule a instance of a BO that sends an email to an SMTP address outside our network. "address error. [CrystalEnterprise.Smtp]: [Error sending address(es) to SMTP server. Return code: [SMTP 550 - Requested action not taken: mailbox unavailable.]. Reason: [email@example.com, firstname.lastname@example.org].]"
I have successfully run the objects when they send to an internal Exchange address, but outside SMTP fails. I can ping the Exchange Server from the SAP BO server and I have a Receive Connector in the Exchange server that allows SMTP relay from the SAP BO server. I'm not quite sure what else to check. Any thoughts?
