So, ecommerce module sends email with no problem, while the Registration widget logs this error:
Message : Transaction failed. The server response was: 5.7.1 <unknown[ip address]>: Client host rejected: Access denied
Looking at the decompiled code, I can see that the ecommerce module is using a simple System.Net.Mail.SmtpClient while the Registration widget uses a Telerik..Sitefinity.Web.Mail.EmailSender.
Could it be that the EmailSender somehow messes up the authentification. Ours use the email address as the user name...
