Erin, I don't use Windoze much these days but here goes:
1. Get a command prompt e.g. Click Start, find Run..., type cmd and press enter
telnet smtp.1and1.com 25
3. If it says something like "trying 22.214.171.124" but never connects then something is preventing the connection on port 25. Try swapping 25 for 587.
If it does connect it will say something like:
[user@localhost ~]$ telnet smtp.1and1.com 587
Connected to smtp.1and1.com.
Escape character is '^]'.
220 smtp.perfora.net (mrus2) Welcome to Nemesis ESMTP server
bearing in mind that the windows format and details may be slightly different.
If you get connected you probably don't need to go any further (the router / firewalls are behaving!) - the problem is not with the network.
If you don't get connected on port 25 try your isp's mail server on 25 - if that connects and 1and1 doesn't then the ISP is probably the problem.
