Replying to some emails doesn't work

[LadyLurcher]

Hi

I am having an issue where when I reply to some emails, it seems the email does not get sent. No error message(s) are shown, and the emails do not show in my sent items (or any other folder).

My replies are to people / addresses I have emailed before with no issue, and it doesn't happen to all my replies. 

I'm using the mail app on iphone, but I have checked in the web mail and there is nothing there either.

Any help would be appreciated!

Thanks

There are issues with the Apple app on iPhones with Sky email accounts so it might be worth replying to these emails via web Mail instead until the ongoing issue is fixed.
