There are 2 old alternate email addresses that I need to delete. I can only find a way to add new ones.

I am able to access my personal Yahoo emails form my phone, but I also have a business account with Yahoo and those are the emails I really need to see on my phone. I use the same log-in for both email accounts but I do not know how to get to my business emails on Yahoo! Mobile. Does anyone know how to do this on Yahoo! Mobile?

Have a business email account through Yahoo which hosts my website. I can receive emails on my iPhone for the business account but cannot respond or forward any of those emails. Is there a way I circumvent this?

someone is sending emails from my business account or has somehow hijacked my domain name and is sending emails and i am receiving the rturned emails. what do i do?

I would like to be visually alerted when messages are received in my inbox,please tell me how.

I have a small business email account. For 10 days we are not ablle to recieve any email to our accounts.
Can you help?

Example: my business email for instance is yoyo@yahoo.com, and some days I receive spam email from yoyo@yahoo.com, and it is spelled exactly the same, and if I email it back to it, I will receive an email from myself. How do they do it?
