Title: Sending mails using SFML
Post by: Niely on February 28, 2015, 04:42:26 pm

Hello

Does someone know how to send a mail with SFML C++?
My idea was to use TCP sockets, and send SMTP commands to the SMTP-server; but it ain't working.

This is my code:

sf::TcpSocket socket;
sf::Packet packet;

socket.send("smtp.gmail.com", 587);

packet << "Hi there!";
socket.send(packet);
packet.clear();

packet << "MAIL FROM: mymail@mail.com";
socket.send(packet);
packet.clear();

packet << "RCPT TO: mymail@mail.com";
socket.send(packet);
packet.clear();

packet << "DATA";
socket.send(packet);
packet.clear();

packet << "Message2";
socket.send(packet);
packet.clear();

packet << ".";
socket.send(packet);
packet.clear();

packet << "QUIT";
socket.send(packet);
packet.clear();
 

I get no compiling error, but I just don't receive a mail.

Thanks for reading,
Niely

Because google's servers are laughing at your connection attempt (there isn't even a connection opened). All I can say is, you got a long way to go and I wouldn't suggest you trying to do this yourself. Instead go find some other library to do this for you.

SFML does not contain any SMTP specific functionality. You'd have to use raw sockets and manage the SMTP bits yourself - or, as mentioned above, use a different lib for the mail bits or just call out to some external program like mailx, sendmail or similar.
And btw; just because code compiles doesn't mean it will do what you want - not even close.

1. Connect your socket (RTFM!)
2. Don't use packets, they have their own internal protocol that Google doesn't know about
3. Use port 25

Then it should work, it's pretty straight-forward to have basic e-mail functionality. For a full client though it's a little more complicated, especially if you want a secured connection.
