This is a real shot-in-the-dark, but I've seen size problems like this on two occasions, one on a web server I wrote and another when I was doing the SMTP email for our campus mainframe back in 1984. It is buffer size related. For short data streams, a buffer never gets filled, so when the first buffer gets sent, all the data goes. For longer data streams, the first buffer fills and goes, but the second (or last?) buffer just sits there because nobody did a flush or set the "push flag" (never mind, you gotta be a real TCP/IP weenie to know what the push flag is all about). If you have the source code to the program "writing" the mail message could you check to see if the output is getting flushed or closed? -- Charles B.
