    This code does not handle long lines correctly:

         ...
         } else if (state.linelen == 0) {
                        state.eof_stdin = 1;
    #ifdef DEBUG
                        if (opts->debug > 0)
                                log_line(LOGPRI_DEBUG, "EOF on input server");
    #endif
                        smtp_write_out(&state, "QUIT\r\n", 6);
                        continue;
         } ...

    but linelen = 0 when the first 1024 bytes of a partial line are read:

            /*
             * Look for a newline in the buffered data. If one isn't found, then
             * either there isn't a full line to read yet, or we've filled the
             * buffer, so we have to return a partial line.
             */
            ptr = memchr(line->buf, '\n', line->bufused);
            if (ptr == NULL) {
                    if (line->bufused < sizeof(line->buf))
                            return 0;

                    linelen = sizeof(line->buf);
            } else {
                    linelen = (ptr + 1) - line->buf;
            }
