Could anyone please help me this anoying mailbox full error. Would appreciate your help for this issue. Regards, ray Hi. This is the qmail-send program at mr-hn.vnn.vn . I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out. <ray@example.com >: Warning: undefined mail delivery mode: normal (ignored). The users mailfolder is over the allowed quota (size).

Hi Ray, I suggest you review the message header of the NDR message to check whether your Exchange server generate the NDR message. If the NDR message is not generated by the Exchange Server, I suggest you enable SMTP log on the Exchange Server SMTP Virtual Directory and have the external sender to send a message to you to reproduce issue. Then, please review the SMTP log to check whether the remote server attempts to connect to your Exchange Server to deliver the message. If the remote mail server does not connect to your mail server, I am afraid that you have nothing to do on your end. Note: I assume that the Exchange server receives email from external mail server directly.
