How to send email from your LCN hosted website

This guide will explain restrictions which affect the sending of emails from scripts on the LCN web hosting platform. For customers using LCN Web Hosting or WordPress hosting.

These restrictions are in place to ensure that email sent from our network is legitimate and follows best practice, which in turn will protect the reputation of your domain and our network.

Please note: If you’re unsure if this affects you, please speak to your web designer or developer and they’ll be able to advise further.

Let’s get started…

What restrictions are in place?

When sending email from scripts on the LCN web hosting platform, customers should ensure that the sender and envelope sender is either;

  • An email address hosted with LCN, that is located on the same LCN user account as the website hosting.
  • An email address hosted elsewhere, such as Yahoo, Gmail or a domain name hosted with another provider.

How do I change the from address?

If you’re using a CMS system such as WordPress or Joomla, by default the sender address will be set as the administrator user. We have included some guides below for popular CMS’ on how to update this email address.


If you’re using a custom-built website, we’d advise speaking to your web developer to ensure that your website sends from an address which meets the above criteria.

Why is this restriction in place?

This limitation is in place to stop other LCN hosted accounts being able to imitate/spoof your domain name on outgoing emails. This is designed to protect your domain, company image and the reputation of our network.

What will happen if I don’t do this?

Unfortunately, your email won’t be delivered. Depending on how your scripts are set up it’s also unlikely you’ll receive a bounceback to inform you of this. If you do, however, you’ll get the following error:

"Mail appears to be from a domain you're not authorized to use"

With this being the case, we’d strongly advise testing any mailing scripts/contact forms to ensure they’re delivering correctly before making them live.

That’s it! By following this guide, you should now be able to send email from your website hassle-free.
