''Content-Length:'' '''


The size of the body of the message System V Release 4

The Content-Length: header describes the exact size of the body of a message. The size is always a decimal expression of the number of bytes occupied by the body:

Content-Length: 5678

It is used by some MUAs to find the end of the message in a large file of many messages. It is always created or added by MUAs or delivery agents and never by MTAs. It should never be declared in the configuration file.
