My account redirects to some @gmail.com address.
Some days ago, something weird happened on routing messages, and the sender received some undelivery notifications with my real address.

Can I prevent from this ?

can you provide some more details?

OK let's have some more details.

I have registered to a mailing list as <something>@xoxy.net. I have set <something>@xoxy.net as an exclusive sender so there is no limit to the mails I receive.

<something>@xoxy.net redirects received mails to <me>@gmail.com.

This week, someone on the list just sent a message like :

Each time I send a mail to the list, I receive undelivery noticfications for <me>@gmail. com. What does it mean ?

hmm... Have you seen one of those error messages? Could gmail be rejecting the messages for some reason? That's what it looks like. Do you receive list messages on the gmail account?
