Jason,
Thanks for trying to help.
1. Screen shots of what? I'm not quite sure what you mean here.
2. I use Office 365 service to send and receive email. The exception is below. In this scenario, MS365 is only used for receiving the email.
The crux of my investigation is that I am trying to prevent our email newsletter going into my junk folder. This email is sent via the following route: Access database emailer > relayed via internal SMTP server > socketlabs 'SMTP' provider > Recipient. It was socketlabs who suggested I add 'Email-OD.com to your SPF record'. I assumed they meant MS365 spf record, but now I'm not so sure.
You mentioned 'Just add that TXT record'. Could you give a bit more detail exacly what and how please?
Thanks again,
Ben
