The sender is not the sole criteria you can use to block messages. It would be technically feasible, but very difficult, to block almost all phishing messages crafted to appear to come from Fastmail...

As I understand it, the A record for mail.domian.com tends usually only to be used for services like OWA that allow browser access to the mail service. However, I have a vague memory that Fastmail...

In order for emails sent from Fastmail to be using SendGrid, it implies that they would need to be using SendGrid's SMTP servers, not their own. I have never seen any evidence that Fastmail has ever...

Any suggestions we make must acknowledge the most important clue: the same user and password works with Thunderbird. Also important is that Fastmail claims that their servers do not see the...

I have used older versions of that tool. Like the Windows tool you can use to try to solve problems with devices (such as sound) I have found it rarely does anything useful. Worth trying, of course.

One thing I forgot to suggest earlier that, at least, changes the way Fastmail is contacted by the client, is to use Fastmail's proxy servers. Take a look at...

I remember this being explained in the past as a security best practice, not something that is enforced. As far as I am aware, this is still true.

When it comes to security around bank details, paranoia is healthy. Your fear of a worst case scenario will more often than not prove to be (thankfully) unfounded. However, a failure to react when an...

Were you able to get Outlook 365 to accept the instruction to allow you to set up manually?

If not, as I recall, there is a setting that suppresses testing the connection after setting it up, which...

Odd. Outlook 365 seems to be ignoring your selection to set up the account manually.

Aside from that, did you set up an app password, or try to use the main account password (which will not work).

And yet, Fastmail is telling you that there is nothing in their logs. Any such rejection must end up in their logs, surely. That is what makes me think that the message is being sent to the wrong MX...
