I have emails sent to one address also sent to another address.
Is this your ISP mail, or something like Google Mail, or Hotmail / Live Mail ?
I'm not after your e-mail address, but it is awkward to know where to start if one doesn't understand the service being used. In my case, I have some free mail accounts on Google Mail, FastMail, Live.com and Yahoo.com. I've also paid for service on Runbox.com and FastMail.net and there's e-mail service at my ISP (PlusNet) too.
I have set up some rules on Google Mail, so incoming mail from some places gets forwarded on to one mail address that I check regularly.
I want to add another address for emails sent there to be sent to my main email and can't remember how to do it.
My ISP PlusNet allows a user to create mail 'aliases' so I could have @myuseraccount.plus.com sent to @myuseraccount.plus.com
But they also allow for mail to be sent to some other mail address (eg @orange.net ) so I could get a text alert about new mail arriving.
I think it would help if you explain which company/ISP mail service you are using and at least give an example where you put xxxx instead of your own username...
eg people can mail me as [email protected] but I want to have mail sent to [email protected] to also go to [email protected]
