The email server thinks your trying to 'relay' through it. In the good
old days, an email server would happily accept a message from (for
example) and deliver it to
without checking the sending or receiving
domains at all. And then someone invented spam. So now, email servers
check to make sure that either the sending domain, or the receiving
domain, is the same as the domain they were setup to cater for. If
neither match the server's own domain, then you are considered by be
'relaying' through it, and very few servers will allow that these days.
In fact, ones that do will usually find themselves on a blacklist.

Having said all that, I still can't say exactly what's wrong, but I hope
you have some idea of what the email server thinks is going on. Most
likely is that your sending account is configured with an email address
that the server is not configured to be a host for. It doesn't normally
matter what the receiving email address is, because otherwise no-one
would be able to send email to anyone :-)

Often to access this, you need to change the port number though, as the bog
standard one does not offer the facility. You often find this when you are
allowed to send from outside your isps network.

It looks like you are sending through a plusnet SMTP server. They will
only accept un authenticated SMTP requests from users with an IP that is
inside one of their net blocks. If you attempt to connect from an
external IP, then you also need to authenticate to demonstrate you are
one of their legitimate users.

Which email client are you using?

I would suggest you look what the email client now requires and set your
SMTP setting accordingly for the email domain address.

It does suggest they are clamping down on their server being used for
spam. Not a bad thing.

True, but he hasn't/isn't
I suspect that plusnet has added some net blocks and not told their smtp
relay about them yet.

The connection is via a plusnet web connection, not a plusnet mail server
The same problem is happening with other servers in other countries,
makes me think it's our US based mail server provider changing the
software. This is on outgoing mail only.

Does the provider provide SMTP submission port 587 (or perhaps legacy

Yup, fair point - I just looked at the IP and did not recognise it as
one of their normal netblocks.

Sounds plausible...

Also some SMTP servers are getting more touchy about the types of

the error)

The five mail servers I use all only allow encrypted connections and its
a good thing IMO.

Even my own, which I don't currently use, is configured for encrypted only.

That is not a message rejecting mail from a web server, but from the

Generally yes, unless you need to maintain email working on a legacy
platform that does not have modern email clients.
