Hi All

I've seen similar topics from a year or two ago, but nothing recently.

It says that the cert was issued by Sectigo RSA Organization and seems to relate to Talk Talk businessess, but the warnings about continuing are dire, so don't know what to do next and can't even phone Talk Talk currently!

Any help fratefully received.

PS - I have a Tiscali email address if that helps?

@Godbotherer The issues that you're seeing look to be the same as the issue that I reported here:

My 2p's worth is that this independent link (which checks the security certificates of TalkTalk's mail server) confirms that it is ok to ignore the warning and proceed:
