Yes I can send it via Webmail but not by Outlook
I get no bounce back or error messages.
I have contacted the recipient and my email does not go into their spam folder.
They can reply which I then read in Outlook but I cant reply unless using Webmail which is very awkward as it is a business contact and I need to send them PDF documents from my PC
I'm not sure if there are any other domain names that have problems.
