PEAR: Mail includes?

I've been trying to get an SMTP mail script working with PEAR.
The server I'm working on has some security issues so it cannot connect out to the internet itself (in say a browser) but can be remotely accessed through company software and actually hosts a website. So any files I need uploaded I have to request to get someone to download and physically go to the machine and put them on.

And so when my use of PEAR's mail function keeps telling me I need new included files that it's not finding, I'm wasting days to get them.

I've got a basic windows install of PEAR for win 2k3 server.
I've got the Mail package downloaded and put Net_SMTP/SMTP.php into NET/SMTP.php (as that was the package I was directed to when I was getting include errors for Net/SMTP.php). Now I have one for NET/socket.php.
I can get the NET_socket package downloaded but that'll take another two days to get someone to put it on the server.

What other packages will likely to be needed here?
Digging through pear.php.net hasn't helped me out.

Thanks,

http://pear.php.net/package/Mail/download/ tells you that you need Net_SMTP, and http://pear.php.net/package/Net_SMTP/download/ then tells you that you need Net_Socket (and optionally Auth_SASL, but not in your case). Finally, looking at http://pear.php.net/package/Net_Socket/download/, you'll see that there are no more dependencies.

Ahh so I'm on the last one I need then.

Thanks for the info.
I was just getting confused looking at different Net packages.
