| Description | Unable to deliver mail to all recipients. The total number of recipients exceeds 32766. |
| Event Information | According to Microsoft : If a new message is delivered to the Internet Mail Service, the server sends a 452 response when the number of recipients being submitted exceeds 0x7FFE. This response is an indicator to the sender that another message needs to be submitted with the remaining recipients (in other words, that the sender needs to break the message into multiple messages with fewer recipients on each message). Up to 0x7FFE recipients the SMTP Command/Reponse pair would look like this: SMTP: Command = RCPT TO: USER@MAIL.COM SMTP: Response = 250 OK - Recipient <USER@MAIL.COM> For every recipient after this, the following command/response pair would result: SMTP: Command = RCPT TO: TOOMANY@MAIL.COM SMTP: Response = 452 Requested action not taken: Exceed Recipient Limit.
