I’ll describe my problem that’s been reoccurring for the past few weeks. I’m unable to:
- Change the support email or email sending email.
 - Sign up or sign in to my account via my forms.
 
However, for some reason, I can send posts via email without problems.
This is all on my local Ghost installation, I reconnected Stripe to test mode and this is my config.development.json file:
"mail": {
"transport": "SMTP",
"options": {
  "service": "Mailgun",
  "host": "smtp.eu.mailgun.org",
  "port": 587,
  "secureConnection": true,
  "auth": {
"user": "postmaster@mg.domain.com",
"pass": "private API key"
  }
}
},
I also tried port 465 with and without securedConnection: true line but without luck.
Based on your previous answers I also contacted Mailgun support where they said there’s no problems or restrictions in my account.
I have no idea what I’m doing wrong and would greatly appreciate if you looked into it.
