Also wanted to know what exactly is the \"Internal Server Error\" and more details regarding that and its status code( is it 500 error ) ? \r\nWe have an automated email blast send that goes out at 1:00am ET every day. Because of the above error, our email send fails every alternate day and has become a big problem. Also wanted to know, why does it work on a day and fail on another day.\r\n\r\nPlease look into this asap.\r\n\r\nThanks,\r\nArchana Mandhare\r\nSr. Software Engineer, PMC\r\n\r\n\r\n"}}
