luceos this is strange. I did this, pasted the key into the email settings of the flarum. Then clicked "send" in "Send Test Mail". And I got the answer "Test mail sent successfully!". But I didn't receive an email. When I refresh the page in the email settings, I get the error "The mail mailgun domain format is invalid.".
I wrote like this
postmaster@sandbox(here is my individual number from the mailgun).mailgun.org
What have I done wrong?
I tried Google SMTP before, but I didn’t succeed with it. It doesn't matter to me which SMTP to use, I just need to connect the registration, maybe there are other services?
