Originally defined as the third audio format of the MPEG-1 standard, it was retained and further extended—defining additional bit-rates and support for more audio channels—as the third audio format of the subsequent MPEG-2 standard.

The same message body appearing many times is therefore bulk email. Proxy server topic Communication between two computers shown in grey connected through a third computer shown in red acting as a proxy. This page was last edited on 20 Augustat The program can be integrated with the mail server to automatically filter all mail for a site.

The server responds with the number of times it has received that checksum. This allows a large reduction in file sizes when compared to uncompressed audio. Likewise, repeatedly sending the same email to a server increases its number in the server, and, therefore, the likelihood of it being treated as spam by others. Some of the protocols in the XNS suite were lightly modified versions of the ones in the Pup suite.

Bulk mail can be identified because the response number is high. The combination of small size and The same message body appearing many times is therefore bulk email. It provided general purpose network communications, internetwork routing and packet delivery, and higher level functions such as a reliable stream, and remote procedure calls. DCC identifies bulk email by taking a checksum and sending that checksum to a Clearinghouse server.

Likewise, repeatedly sending the same email to a server increases its number in the server, and, therefore, the likelihood of it being treated as spam by others. No technique is a complete solution to the spam problem, and each has trade-offs between incorrectly rejecting legitimate email false positives as opposed to not rejecting all spam false negatives — and the associated costs in time, effort, and cost of wrongfully obstructing good mail.
