Recipient error. : CrystalEnterprise.Smtp

Question

Hi, am getting this 'recipient error. : CrystalEnterprise.Smtp' error in a Business Object Crystal report. I am able to send mail to the recipients but the report status is fail. The report was running fine for a while and now it is giving this error. If we run the same instance it is running good. But our new instances are not running fine. Kindly help me on this error.
Regards,
