[Help]Sending Email

[258456]

How do i send emails with c++. I google and found out about POP3 and SMTP but idk how to use it. Your help is appreciated. Thanks.

To send e-Mails with Code, Start by knowing how Mail Servers/Protocols Works =).

POP(3)/IMAP/SMTP = Protocols.

Edit~

Okay ; I admit my answer wasn't convenient, But You give me that feeling ; Let me explain myself.

I often see you post thingys about new thingies and never you trying to go far/further in something, Only ask for basic things you don't know and overview without trying to understand, And In my opinion of coding this is not really a good thing to do if you want to learn instead of Paste...

Ok can't really find any good tutorials so can someone exlain it? All I know is that it involves windsock programming

POP3 is for incoming messages.
SMTP is for outgoing messages.
