Hi @timbrns!
Thank you again
But sorry I think you got me wrong (or I did not explain my self clearly 
)
- install production
- go to the backend and set a valid working SMTP email server provider (My SMTP server is provided by mittwald.de)
- Go to frontend try to create an account, fill the form and on the email field paste this „asdfasdfasdfkljkldsauhiuweqn@iasdfklnhjkaeiuqwoerqcwnqerw.com“
- Click continue
- Get error
It seems it has to do with the email provider response „Recipient address rejected: Domain not found“, and SW6 cant handle the response
(My SMTP server is provided by mittwald.de)
If you go back to the backend the account is there, the password works, everything on that account is fine.
Is just SW6 crash on a „Domain not found“ SMPT server response
If you create the account with a valid email domain, everything works, no errors and email gets delivered
