is anyone using a public site and sending an email with this public sites user through an apex class with the SingleEmailMessage Method. It always worked very well but since some time i get the error message:
"NO_MASS_MAIL_PERMISSION, Single email is not enabled for your organization or profile. Single email must be enabled for you to use this feature.: "
Did salesforce some changes to the public sites user permissions. My current permissions allow outbound messages in the public access profile.
I cannot find any other permissions, and I am using exactly the same functions for other processes with internal users, there I it works fine problem.
