I've recently starting having problems with some emails bouncing back from some clients. Majority of emails are sending fine. (also a few are going into clients spam boxs)
I use Entourage (same problem on MacMail as tried from that too) and have had these error messages from two client's email addresses:
Returned mail: Sender Authorization check failed - psmtp (from newsint.co.uk.s200a1.psmtp.com)

and

My web hosting has recently changed server (last Friday). But if I send directly from their browser mail app it works. I've contacted them and they can't find a problem
I've also recently upgraded to superfast brioadband and I've had my BT email changed. Am I using the right SMTP server for out going mail smtp.btconnect.com?
Looking on the help it says it should be smtp.outlook.com but I can't get this to work. Even when I sent up my Bt email address in Entourage to the exact settings. I can't get this email to work
Any idea of what it is. Is this BT outgoing server causing the conflict or my web hosting. Please help, it's driving me crazy
