Mail Delivery failed


New Email
Hi guys, hoping for some help here. I'll try to explain as best I can!

Recently I changed ISPs - twice within a few months.

Originally my email address was:

It then became

It is now

Ok, I also have another email address which is hosted through Planet Domains, as a business email. It is (I will call this CC)

When I made the most recent change to my ISP and email, that being I also re setup my CC email to come through Incredimail. As far as I know I have all of the correct settings, however when someone sends me an email to the CC address they receive a Mail Delivery Failed message, even though I actually RECEIVE the email.

Here is an example, and you will notice that it is still referring to the address for some reason.

Hi Deb,

I think you realized that is the problem email address.

Why is it getting email? Do you have a copy+forward configured in your account? Do you have a mail filter or rule somewhere either in incredimail or your ISP control panel that is sending copies of incoming email to that address?

Thank you so much for replying - it's nice that SOMEONE did LOL.

I have resolved the problem myself - as you suggested I had set up forwarding for my Custom Companions email through the host, and although I had already looked for this, I was not looking in the right place.

Thanks again :)
