The connection doctor shows that the connection is being rejected due to the HELO that is sent to it:
HELO mymac.mydomain\.co\.uk
501 HELO requires valid address
I have reproduced the above error with a telnet to the SMTP server. With mymac.mydomain\.co\.uk I get the above error. With mymac.mydomain.co.uk it authenticates correctly.
I don't know why it is adding the backslashes. How do I stop the macbook sending a garlbed HELO ?

I'm guessing it's set to mymac.mydomain\.co\.uk or mymac.mydomain.co.uk at the moment? If it's set to the former then try removing the backslashes. If it's set to the latter then try changing it to a single word like 'mymac' or something similar.

I have got it to work by using another mail client (thunderbird, also ms-outlook). However I would like to understand why the mail prog supplied with the computer does not work on an out-of-the-box computer.
My limited understanding of OSX is that it does machine naming differently to Linux (which I am expert on) and Windows. I believe the system preferences->sharing is where it's done but I really don't understand enough to confidently set it up and any proper documentation seems rather lacking.
I have a "computer name" like "My Mac" and it shows as "mymac.local" just below that. It does not seem possible to change the ".local" bit.
If I go to system preferences->network then DNS, I have "mydomain.co.uk" listed under the searchdomains box on the right.

I have just noticed that the Remote Login page of the System preferences->Sharing screen shows "To log in to this computer remotely, type "ssh myname@myhost.mydomain\.co\.uk" - it has the backslashes in it.
Now the only place I have found the domain name displayed is the System Preferences->Network screen, on the DNS tab of the Advanced screen where it is shown under Search Domains and it is there but greyed out. It does not include backslashes.
If I type domainname in a terminal it just returns nothing. If I type hostname it returns "myhost".
I can't believe that setting up networking on a machine hyped as simple can be so damn hard

You could try over writing it in the settings with something else, see what effect that has.

Quote from: starfry Now the only place I have found the domain name displayed is...
Is the domain name as you've typed it here or is it in the format <username>.plus.com?
Edit: also found this but it's not overly conclusive. Perhaps explicitly setting the DNS servers on the macbook air might help? If you do then I'd suggest using one of ours (212.159.6.9, 212.159.6.10, 212.159.13.49 or 212.159.13.50) and a third party's like google as secondary (8.8.8.8 ).

If I do "scutil --dns" it shows the search domain correctly as "mydomain.co.uk " with no backslashes in it. However the sharing gui screen shows it as "mydomain\.co\.uk " and attempts to HELO an SMTP server also use "mydomain\.co\.uk " and the PN SMTP server borks on that.
I also found that link but came to the same conlusion as you.
Re DNS servers, it is correctly using my network DNS (none of the machines on my network directly query the PN ones).
