Hello,

When i try to create a user i get an SMTP error from my SMTP server. Apparently i am not allowed to use the email address "admin@localhost" as a sender (from) email address. However, i have updated the admin user account and changed its email address into something that should be valid (i use my own user email address). Yet i keep getting the error that "admin@localhost" has an invalid domainname. How can i change the "admin@localhost" into something else so this error will disappear. As i said before, i already changed the email address from the user admin on the user accounts.

Following the error i get:
