Emails not working?

[mikelons]

Hi I have just spent 4 hours trying to fix my php form script that wasn't broken.It seems that my email account is having an issue with receiving emails when a user on my site enters their email address into an input field, where their email providers are @gmail @hotmail etc.I entered test@test.com & someone@somesite.com into the email field and the email was received immediately in my inbox, however all others have failed to appear.Is there a stupidly huge delay with the email system or is there an issue on your end. This was working perfectly fine a few months ago before the kernel update. If you need to see my php script just let me know.Any help will be greatly useful.Mike.

Hello,

To further investigate this we'd need to know what email address you are sending these too, that would help us find them in our logs.

They are being sent to mike@mikelonsdale.co.uk,
However I tried sending them to my personal email address and the issue still persist.

Thank you for your quick response.

I tested a few email address in my php form. It seems that the only email providers that are getting blocked(that I've tested) are:
@gmail.com
@hotmail.com
@yahoo.com

Emails that did make it to my inbox(that I've tested) are:
@karoo.co.uk
@me.uk
@icloud.com
@hotmail.co.uk
@gmail.co.uk

Seems strange that some email address that are being submitted to my form are not coming through were others (even if the address is with the same provider, just with a different domain name) are managing to come through.
For example email addresses ending in @hotmail.com are not making it to my inbox but hotmail.co.uk are...

Hope this helps someone find a solution.
