Firstly apologies for posting here. I’ve tried for a day to resolve the issue myself. Subquently I contacted my shared server website hoster, however they’ve just pointed me here.
If Cloudfare is disabled/paused all appears to be working, both my email client (thunderbird) and the contact form on the website. If I enable Cloudfare I am no longer able to check mail through thunderbird and the contact form times out. I have played around with the orange and grey clouds, however had had no luck where both the CDN (when testing through gtmextrix) and email work togther as designed. Please see a screenshot of the current settings.
Can anyone offer any suggestions on how to get this setup correctly?
