Messages sent through your servers are usually received without problem.
Today however they are rejected due to 'the sending mta's poor reputation' and returned.
Sending the same message via gmail is without problem.
What's up doc?
Fixed! Go to the fix.

Thanks Harry,
I attach an image of the headers etc from the returned message.
I have deleted the message body and two attachments, an image(jpg) and a pdf file, from this message.
I hope this data is adequate and I'm grateful for your help.
As I remarked, the same message + attachments went via gmail without problem

Getting this today with my place of work not accepting emails from my home email address. Is this PlusNet or my employer that's causing this issue?

Is this still happening? One of the Plusnet relay servers was on a block list for a while earlier. It should be OK now.

It depends ... I have just checked PN's MTA (mx.avasin.plus.net) and it is not black listed. However from other environments I support I am aware of some mail sever operators (receiving systems) using less than reliable BLACK LIST services which deem perfectly "good" MTAs to be black listed. This arises out of a combination of using out of date data and poor quality tools for blacklist management.
To know what is in play here, we would need to see the full (but redacted) rejection message.

Two test messages, with attachments, to the same recipient have arrived without fault.
Whatever the problem was it has now, for me, disappeared.
Hoorah.

Oh no it didn't........
See below for a repeat to the same address....
Do I need to say that gmail worked like a charm....so I reckon it must be Plus that has a bad reputation?
Should I be moving elsewhere?

Any chance you can PM me the full unedited version of that message so we can get this looked at further.

No, I won't do that: it contains medical references for the recipient only (I hope).
I will send a PM with an edited, vanilla, version if you wish.
I do appreciate your efforts to help but, as I have said, there is no problem when I use gmail with the same message...

We'd need any email addresses or URLs left intact as it's likely to be these causing the issue. Other information from the body of the message shouldn't be an issue if it's removed

HOWEVER it is not unknown for email servers using poor quality black list checking services to incorrectly deem a server to be black listed.

Thank you for the review of possible causes;
you made the point about black lists some time ago and, as I am uncertain what 'inadequate AV controls' means, I am unable to assess whether that might apply to my system.

I had not intended to imply that this applied to your system and that the absence of such on your system might specifically cause the problem you are experiencing.
The infection of one system exploiting the plusnet email relay service could be sufficient to damage its sender reputation for everyone. An email system I provide user support for, used by just a few hundred user had two accounts hacked ... resulting in the (single) outbound smtp server becoming all but unusable to any email service running aggressive anti-spam filtering.
