Did you or someone else who might have gotten into your account create a mail filter rule that sends a copy of all your emails to a different email account? If you got hacked this could be a way for someone else to receive password reset information for your accounts without your knowledge.

Thanks popwich . but i'm sure that there is no filter rules , i'm making reset to the password and can send emails but there is one email address when i sending to it , it bounced back to me with failure (Leddo_2007@yahoo.com) i guess that this email perhaps not working properly or has any problem.

Thans popowich , i'm certain that there is no filter rule and i'm reset the email password and could send emails but there one email bounced back to me with failure mailer (leddo_2007@yahoo.com) i think that this email have a problem , i wait yours reply.

Hello,

I see, if it's only one address giving you a problem then it's likely their account or configuration.

I tested the email address and it appears to be valid.

250 recipient <leddo_2007@yahoo.com> ok

If it is being reported to you as not being a valid account then maybe they added you to their block list.

I'll have to test that and see what kind of response happens when the email is From: a blocked account and To: the account that created the listing.

Also, you should check the reply-to and any address book entries for typos and extra spaces or hidden characters in their email address.
