Article PS01122781 503 Need Rcpt command error Problem Description When trying to send an email message with AspEmail, the following error is generated by the Send method: Persits.MailSender.4 (0x800A0006) 503 5.5.2 Need Rcpt command. Other variations of this error for different SMTP implementations include: 503 5.0.0 Need RCPT (recipient) 503 must have sender and recipient first 503 Need RCPT 503 Need RCPT (recipient) 503 No recipients specified 503 No recipients: need RCPT 503 RCPT first (#5.5.1) 503 Unexpected command or sequence of commands Solution Most probably, this error means your script is not calling any of these methods: AddAddress AddCC AddBcc As a result, AspEmail gets no recipient addresses to send a message to. Check the logic of your code. If you are calling AddAddress/AddCC/AddBcc in a loop, make sure the body of the loop is entered at least once. For example, if you are looping through a recordset to obtain your recipient addresses, make sure your database query returns at least one record.
