Yahoo Mail rejects the Trello Inbox alias address

[Torschtl]

I used to send e-mails from a Yahoo e-mail account (***@yahoo.de) to my Trello Inbox using the alias e-mail-address provided by Trello (mytrellonickname+***@app.trello.com).  (My Trello account is associated to a different e-mail account, not the Yahoo account, that's why I can't simply use the "inbox@app.trello.com").  

It has worked a few times, but recently Yahoo's in-browser e-mail app no longer accepts the Trello alias address.  Yahoo says I should use a correct email address. 

Did anyone experience the same issue and knows a solution to it?

Hi @Torschtl ,

Welcome to the community!

Did you try resetting your Trello 'Email to board' email address? You can do this by going to your board settings and selecting the "Email to board" option. There, you can reset the email address and try using the new one. If you're still encountering issues, please note that the format should typically be: yourboard+unique@boards.trello.com  (not @app.trello.com for most users).

You might also try sending from a different email account or using Yahoo’s "classic" webmail interface, if available, as it might have different validation rules. If the address is correct and the issue persists only with Yahoo, it may be a limitation on Yahoo’s side, for which there is no fix from Trello's end.

Thanks for the explanation!  I was indeed a limitation on Yahoo's side and can't be solved from Trello's end.
