Hi Ester and Welcome. I'm Joel and I look forward to assisting you today with your question. Do you access your Yahoo mail via the web or using an email client like Thunderbird? It is possible for someone to send you emails and fake the sender address (reply to). So your saying that the emails are coming from different senders each time? Is there a reason why you're wanting to save them? It is up to you, but if you like you could attach one here and I can analyse the email headers on it and also the content and check if it is related to any common spam/scams. Thanks Joel
Thanks Ester, I have not seen this issue before. I will opt-out so another expert can assist you.
i think for this one i would have to log in to your system remotely and look at it with you
it might be a virus but it seems unlikely that would affect yahoo through the web.
I have a few ideas of what it might be starting with the person got you on a few xx rated mailing lists. those will keep spamming you from different email addresses but the thing with deleting one vs everything i really want to see. It might have to do with marking them as spam and yahoo deleting everything from that address if you delete one of them
