checkout progress

Hi, can you check what is the problem that i'm having here? It show in my checkout progress but still able to redirect to paypal website, but i afraid it might affect my customer info or something else can you help me identify what problem is that?

Hello,

This error message is just telling you that your server can't send mail so you don't have to be afraid about your customer info. I think that you'll just have to configure your server through "Administration->Global configuration->server tab->Mail settings".
