Mail not delivered
I bought a Tuta Revolutionary subscription and an own custom domain which I have added to Tuta. Yesterday I've been quite busy to add dozens of mail aliases for each and every contact/service/vendor and I'm about done setting those up, informing all services of my mail changes.
Now I notice whenever I send mail to my work emailaddress from any of my aliases, and for example to my girlfriends workmail, the mail will return undelivered in my Tuta inbox, stating:
The mailsystem said 554 Your access to this mail system has been rejected due to poor reputation of a domain used in message transfer.
Both addresses are government institutes in The Netherlands. I can receive email from my work email account.
What about this? Will I be limited using Tuta for sending mail to certain companies/institutes?
