First ill say that I know that this topic has been brough up severel times before. Unfortunately they didn't solve my problem though.

I'm trying to send a simple order confirmation e-mail.

This goes well locally but not when I upload the code to my site.

My smtp-settings look like this:

<smtp> <network port="587" host="asmtp.unoeuro.com" userName="kontakt@*****.dk" password="****" /></smtp>

And the code for sending the e-mail look like this:
I am aware that my customerId is hardcoded, I don't know if that makes a difference.

var emailService = UCommerce.Infrastructure.ObjectFactory.Instance.Resolve(); var localizationContext = UCommerce.Infrastructure.ObjectFactory.Instance.Resolve(); // Find the relevant e-mail profile for the current store var emailProfile = UCommerce.Runtime.SiteContext.Current.CatalogContext.CurrentCatalogGroup.EmailProfile; // Load information for e-mail personalization var purchaseOrder = UCommerce.Runtime.SiteContext.Current.OrderContext.GetBasket().PurchaseOrder; // Set up personalization parameters - params will be passed to // the configured e-mail template var queryStringParameters = new Dictionary(); queryStringParameters.Add("orderGuid", purchaseOrder.OrderGuid.ToString()); //queryStringParameters.Add("customerId", purchaseOrder.Customer.CustomerId.ToString()); queryStringParameters.Add("customerId", "0"); // Send e-mail

emailService.Send(localizationContext, emailProfile, "OrderConfirmation", new System.Net.Mail.MailAddress(purchaseOrder.BillingAddress.EmailAddress), queryStringParameters);

The strange thing is that is is different on the server than when I run it locally.
