You actually want to post a reqular mail without to submit the leter to the post office. So you will need to deliver it manually.

do you mean push the message directly to the pop server of the recepient

Sounds like Winsock...

Hey,

You wanna use winsock yer, you simply need to open a connectio to an smtp server e.g

freeserve.com on port 25

Then where your connected you need to send it commands, such as

mail from: [email protected]

For more info on these commands you should look up smtp telnet tutorials, when you open up a raw connection to an smtp server in telnet, ur doing the same thing in your prog.

I would post you some source, but im on my other pc and my programming folder isnt shared on my network, and i cant go down other end of house... :( so if you still cant do it by tommorow then i will post you some code.

Hope that helps,

Hey,

Ok i take it you havnt done it yet, below is some code of mine to make a simple connection to a server. Sorry, i dont have time at the moment to make it send an email. All you need to do is change the port and the host your connecting to.

Then use Send() and recv() to send and recieve :D

You must make sure you call recv() after you send somthing and when you first connect, otherwise it will mess up. Here are the smtp commands you need to look up to send to the smtp server:

helo //say hello to the server :)

mail from: [email protected] //whos it from

rcpt to: [email protected] //whos it to

data
lalalal //must end with a . on its own line
.


If you wanna go into more depth like Subjects and CCs i dont remember them off hand but there pretty easy to find.

Any way heres the simple winsock code:

Code:
