@JohnD maybe you can pass this up the chain of command and get the information to where it needs to be, so somebody technical can fix it.

The error logs are as follows, this suggests that three.co.uk need to hire better technical staff 🙂

Same exact problem here. It turns out that this is because three's technical support team is incompetent.
Let me dissect this issue for you...
Firstly, three send customers emails from multiple domains, which, is bad practice. In today's age, ideally, customers should be familiar with one or two solidly recognisable email addresses which they can easily identify as authentic. Once you introduce multiple subdomains and multiple emails, you muddy the situation and introduce security risks and vulnerabilities for your customers.
So, let's look at the email addresses which three use during the order checkout process:
@mails.three.co.uk
@servicemails.three.co.uk
@service.mails.three.co.uk
@notifications.three.co.uk
This is where it get's interesting. The first three emails work fine, they are set up correctly, they are secure, they have the appropriate authorisation and security protocols in place. Those emails are the accounts which send the 'order confirmation' and 'customer agreement form'. The reason you receive those emails but not the eSign one, is because those emails are sent from an email address that is properly configured on the server.
Unfortunately, problems arise when we investigate notifications.three.co.uk (which, it appears is the email address used to send the eSign form/link).
It turns out that notifications.three.co.uk domain DOES NOT have a DKIM or SPF record set up. This is awful news for three's customers, and introduces all kinds of vulnerabilities and security risks. Firstly, not having these records appropriately set-up, means that hackers can hijack, intercept or spoof emails to make them look like they were sent by three, when in fact they were not. The reason the eSign document is never received by customers, is because, it is sent from such a vulnerable email. Most email servers will rightfully reject this email without even putting it in the user's spam folder, it will simply be outright rejected and disappear into non-existence. This is because the recipient email server is unable to authenticate the authenticity of the sender.
I've tried to raise this issue multiple times, but, so far it's fallen on deaf ears. Nobody in their overseas call centre cares, nor do they understand English well enough to grasp how serious of a situation this is, and how urgently it should be addressed. This is a security risk.

I’ve been waiting for four days now. Same story - tech support’s “best” solution was to ask me provide a different email address (bearing in mind, I have no problem receiving any minutiae communication from Three to my existing email). They cannot cancel the stuck order either. When it’s finally cancelled (whenever that might be), I am leaving this network as soon as I can.

I’ve got the same problem. Been waiting three days, Been on chat & rung them. Still no further forward. I can’t get on the website either.
