Okay, so I stepped through the code, and apparently, as expected, it is failing at the: 
if (!connect($sock, $addr)) {

[download]

statement from connect() subroutine in the IO::Socket.pm file. Well, if anything, after that call, which is a low level call that I can't step into, all the sudden $! is set to the "No connection could be made because the target machine actively refused it" error and the logic causes it to return with an error.

I mentioned before that I have turned off the Windows firewall, but this is a company issued laptop that has McAfee installed on it. It should only be doing virus scanning, but I can't help but think it is somehow causing the problem. What doesn't make sense though, is that I can 'telnet' to port 25 without a problem. So, unless there is some kind of rule that allows telnet to get to that port and not Perl, I don't understand how that can be the case.

I also have Cisco AnyConnect installed, and it implies it does firewalls, but I think only when the VPN is running, and I don't have it working when doing these tests.

Anyway, if anyone has any other ideas, I'd love to hear them.

Thanks!
