Why is this happening? It's not all my emails that are getting sent there, and it's only started happening in the last 4 emails I sent. I checked my "to" line very carefully and the only email address I have is info@[orgname].org, but [unfamiliarorg]@yahoo.com keeps receiving my emails.
Nobody knows why this is happening. I don't want the other organization to be receiving my emails, and they don't want to be receiving them either. But nobody knows what to do. I suggested setting up a filter on their yahoo account, but that doesn't really solve the problem, as I don't know if this is maybe cause by a virus on my computer or on the NGO's computers.
Help is much appreciated. Thanks!
