Hey Terry,

I suspect it's a bit more complex than filtering of bournemouthecho.co.uk  by you ISP

So focussing on the email you sent to newsd...@bournemouthecho.co.uk to start  with. The reason this failed is that your mail went through 1&1's servers and they identified it as "spammy", they marked it as such (by forwarding through certain servers) and bournemouthechos policy is to block such messages, they then refused delivery and therefore you mail bounced.

The question is why did 1&1's servers identify your message as spammy. It's not immediately apparent to me why as there's no logs to indicate what triggered this. I see you have SPF set up on hadrian-way.co.uk which seems to include the kundenserver.de mail servers which is good as it seems you are sending mail through them.  I think you probably need to reach out to 1&1 and ask why they are marking your messages as spam (unless they have any diagnostic tools you can access?)

My apologies for a very long off topic post, but I could do with a bit of help
here.  I'm been having a problem receiving emails from the Bournemouth Echo
and when I tried query it I had a problem sending to them.

Can anyone suggest what I'm missing?  I've raised this problem with my ISP
(IONOS) but I'm not convinced that they are being totally honest with their
reply that the problem is not caused by their server.  Here is the content of
the message that I tried to send to the Bournemouth echo today:

<Message Start>
I've been registered with both yourselves and the Dorset Echo and for some
time now and have received messages from both journals about breaking news
stories.  Within the last week or two, every message that you've sent goes
straight into my SPAM folder.  This occurs with both of the two Email clients
that I use and also at my Email provider (IONOS), so it isn't just a
misconfiguration in my clients.

Could you kindly sort this problem?
<Message End>

I immediately got a response from IONOS indicating that my message couldn't be
delivered.  Here is the main content of that response (I've omitted a huge
block of random text):

I interpreted that as telling me that Spamhous had bournemouthecho.co.uk on
its blocklist, but when I clicked on the link to Spamhaus the problem seems to
relate to IONOS own Abuse Service.

I did a whois on bournemouthecho.co.uk and got three IP Addresses.  When I
pasted those into the SBL search portal at Spamhous, the response was that
there is no problem.

It seems to me that IONOS is arbitrarily bouncing messages to and from
bournemouthecho.co.uk and then blaming Spamhaus.

Any thoughts on this?
