import std.uuid: randomUUID;
pragma(lib, "curl");
string Message(string To, string From, string Body, string
Subject, string Filename, ubyte[] Content) {
Array!string headers;
string cid, msg, boundary = randomUUID().toString(), Fname =
baseName(Filename);
const string crlf = "\r\n";
int Size = to!int(getSize(Filename));
headers.insert("From: " ~ From );
headers.insert("To: " ~ To );
headers.insert("Subject: " ~ "Subject" );

foreach(header; headers) { msg ~= header ~ "\r\n"; }
