Re: Bouncing Emails

I hope I don't get shot down in flames for this reply.  The IP address 

82.165.159.5

is indeed on numerous blacklists, but it belongs to OneandOne which is, I suspect, is your e-mail forwarder. So you must be using VM to send messages via OneandOne's servers which have been blacklisted. I think it is to your forwarder that you should direct this query.

Please don't send me private messages unless I ask you to.
I do not work for VM. The advice I give is based on my best understanding of VM policy and practice. You rely on it at your own risk.

Re: Bouncing Emails

But keep watching this thread in case I am contradicted. I'm still learning this stuff. But I got the "forwarding bit right" at least!

I'm not going to contradict you here

You're spot on.

Re: Bouncing Emails

Actually, I do feel the need to qualify my answer here.

You don't say what domain you are sending to. and whether you are sending from a Virgin Media address or from your own domain.

The emails in question are being bounced by Hotmail.  However, the server being bounced is indeed a 1&1 server.  Some people rather than host their own email properly, set up mail forwarding to a free email service instead.

Let's give an example.  I have a free address fred@hotmail.com but I also have my own domain example.com hosted with 1&1.  so I set up mail forwarding so that all mail say joe@example.com is sent to my Hotmail address.

I now try sending an email.

myaddress@blueyonder.co.uk -> joe@example.com

Virgin server                              -> 1&1 server

When it arrives at the inbound server for example.com - no mail is stored here instead 1&1 forward the mail on to fred@hotmail.com, while at the same time leaving the sender address untouched.

myaddress@blueyonder.co.uk ->fred@hotmail.com

1&1 server                                -> Hotmail server

Hotmail will, first of all, examine the 1&1 server IP address and check if it's blacklisted.  In this case, it is, so it will reject the mail.  1&1 then deliver the bounce back to the original sender's address.
