We have modified the email address used to send notifications from on your managed Flarum community. Previously this was no-reply@blomstra.net it has now been updated to community-notifications@notifications.blomstra.net. This only applies if you use the default mail driver "Blomstra".
We provide this notifications mail 'as is'. In case you prefer a personalized sender address please configure a different Mail option from the Flarum admin area. We can recommend MailGun and SendGrid, but all email services like Gmail, Outlook etc can be configured. Feel free to contact us if you need assistance.
