Woran erkennt ein Parser nun eindeutig, wo eine Mail endet, bzw die nächste anfängt.
Zitat:
Fortunately, every email has at least one From-line at its very beginning. Every message begins with "From " (From followed by a white space character, also called a "From_" line). If this sequence ("From ") at the beginning of a line is preceded by an empty line or is at the top of the file, we have found the beginning of a message.
