TIP
If you're sending from such an address but it's still not working, please contact AgilePlace Support and let us know:
the URL of the board you're trying to send cards to
The email address you're sending from
if possible, also attach one of the emails you sent as a .eml file
We will then investigate and follow up with you.
Sometimes emails come to our systems from an email server that’s using a security feature called Bounce Address Tag Validation ("BATV”). This adds a "Simple Private Signature" (prvs) tag tag into the sender email address, eg: "sender": “prvs=john.doe@example.com.” Since that doesn't exactly match a user in the account who has rights to create cards on that board, a card is not created.
Contact AgilePlace Support and we can confirm if this is the issue affecting you. If it is, you'll need to contact your email admins about disabling BATV for emails to @leankit.us addresses.
