Whats your soluiton for nopcommerce with cloudflare?

For ssl you should Change a line in the file WebConfig
<add key="Use_HTTP_X_FORWARDED_PROTO" value="true" />

Make sure your smtp server port is 485/587, and your firewall allow out for those port.

Please use the git current Develop version, there are much different with the download version. Also  try yo connect with gmail/Hotmail etc, I am sure it works on linux  for CloudFlare.
