Okay, I think I've done it but I have a couple of questions:
Signed in as email@example.com and set up live domains.
CPanel > MX Entry >
I changed the record which was 0 / mysite.com
to 0 / <string of random>.pam1.hotmail.com
Is that right?
Seems not as I tried sending an email to that address which then came back undeliverable
Although is that because I haven't set up a special user with that email address through Windows Live Domains?
CPanel > Advanced DNS Zone Editor >
I added two TXT domains:
domain.mysite.com. / 3600 / v=msv1 t=<random letters and numbers
domaintrust.mysite.com. / 3600 / <the include "~hotmail.com" thing>
Is this the correct entries here?
Windows Live Domains tells me it's active and okay.
Do I have to set up a special user?
I am signed in as firstname.lastname@example.org, so do I have to create separate users (like email@example.com) or can I just send mail from firstname.lastname@example.org which is added as an additional address, which will then be received as coming from that address (IE, no "on behalf of").
Seems not again, I sent a mail which then said "on behalf of".
So basically, Outlook.com doesn't support me signed in as "email@example.com" sending mail as a confirmed "firstname.lastname@example.org" without sticking "on behalf of" on the email.
Not exactly a difficult request but no wonder so many people continue to use Gmail
