When I click "Run Diagnostics", the ? then changes to a green tick and when I refresh emClient, the test email from Calibre arrives in my emClient and webmail inbox. So I think emClient does something to prove my credentials or something to allow the Calibre test email through. So, as I'm sending the test email to myself, I can see it IS received after I run the emClient diagnostic. I can also see any mobi file is received on my kindle and iphone IF sent by webmail or emClient ... and both go through the same BT servers. The only thing not arriving is any mobi file sent via Calibre, even though the log showed that they were sent and not rejected by the server.

My router always comes back with the same IP address when it's switched off and on again.
Using calibre 4.2, I just sent the test email to my ISP email address, a work email and gmail. It got to the last two, but, my ISP blocked as spam. The spam details are:

Code:
X-SpamDetect: **: 2.839000 Message text disguised using base-64 encoding=2.0, From: does not include a real name=0.8
If Amazon are using similar rules, that might be why they are being blocked.

I also tried calibre 3.45. The test email was wasn't blocked by my ISP. The spam line is:

Code:
X-SpamDetect: 0.839000 From: does not include a real name=0.8
But, sending a book was with the same spam detection.

I have never tried this before, so I don't know if anything has changed recently. And I don't use a Kindle, so haven't tried that. If it is a spam block, I would expect others to be impacted, unless it is just btinternet that is the problem. Maybe something would be obvious from the headers that they add. But, it looks like it is an Amazon issue.
