What is an .ntm file?


A .ntm file will usually be found in the gordanotemp directory. That is the format used to store messages as they are being received on the server. The .ntm file will grow as the message continues to be received. Once the complete message is collected, it is transferred from the .ntm file to the user’s mailbox, a 250 OK is returned to the SMTP protocol to indicate that delivery of the message was successful, and the .ntm file is then deleted.

NTM files are not automatically deleted if a transfer fails. They are kept so that if the remote server attempts the ESMTP option ?RESTART? the remote server only needs to send the remainder of the message. This can have a dramatic effect on the bandwidth required for your mail server, particularly in areas of unreliable Internet conenctivity.
