PHP security update

You may have seen reports of a security issue affecting PHP (the software behind many websites) that affected a number of companies yesterday. Our hosting team has already applied patches across our platform for these vulnerabilities.

If your website runs PHP 7.2 or later, it’s already protected — there’s nothing you need to do. If it’s running an older version, we’d recommend upgrading as soon as possible.

Setting up your email

Your device or mail client should have detailed instructions for adding a mailbox, but here’s everything you’ll need:

  • Account type: IMAP
  • Username: your full email address
  • Password: your mailbox password
  • Incoming server: imap.extendcp.co.uk — Port 993 — SSL/TLS
  • Outgoing server: mta.extendcp.co.uk — Port 587 — STARTTLS
  • Authentication type: Password

Why IMAP over POP3?

With IMAP, you can be logged in on your phone, tablet and computer at once — delete an email on one device and it disappears everywhere. That’s why we always recommend it.

Video guides

Accessing your email
You can get to your inbox three ways:

  1. Through your hosting account
  2. Via webmail
  3. Through a third-party client like Outlook, Mac Mail, or your phone’s mail app

Managing your mailbox

Creating a new email account

  1. Log into your Control Panel
  2. Click Mail Boxes under Email
  3. Under Email Address, enter the name you’d like (e.g. your.name@your-domain.co.uk)
  4. Click Add
  5. You’ll see it listed under Modify Mail Boxes

It can take up to 60 minutes to fully activate, after which you’ll be able to send and receive as normal. ✓

Resetting your mailbox password

  1. Log into your Control Panel
  2. Click Mail Boxes under Email
  3. Enter a new password under Change Password
  4. Click Modify

Your mailbox will be unavailable for up to 5 minutes while the change takes effect.

Running out of storage

Each mailbox comes with 1GB as standard. To check your usage or free up space:

  • Log into webmail at www.outitgoes.com and check Settings — make sure Thread support is switched off
  • Delete anything you don’t need — remember to empty Deleted Items/Trash too, as that still counts towards your storage
  • Back up anything important first — once deleted, we can’t recover it

Need more space? We can increase your mailbox:

  • First upgrade: doubles to 2GB — £20/year
  • Each upgrade after that: +2GB — £12/year (up to 10GB)

Contact the office on 0117 950 2667, or email support@duport.co.uk to arrange this.

Fixing common problems

Why can’t I send emails?

Work through these in order:

  1. Mailbox full? Check your capacity in the control panel — if it’s near 100%, delete some emails or increase your storage (see above).
  2. Wrong outgoing server? It should be mta.extendcp.co.uk.
  3. Password issue? Retype it, or confirm it’s correct by logging into webmail.
  4. Authentication settings wrong? Your outgoing server should authenticate using your password — if SSL is switched on for this, try turning it off.
  5. Wrong port? Use port 587 (or 465 if 587 doesn’t work). Port 25 isn’t supported for sending.

Mailbox connects to webmail but not to a third-party app

Two common causes:

1. Password strength. Avoid reusing an old password, using the same password across mailboxes on your domain, or weak combinations. A strong password should be at least 12 characters, unique, and mix upper/lowercase, numbers and symbols. Check yours with this Password Meter Tool.

2. TLS 1.2 support. Your mail app needs to support TLS 1.2 — Outlook versions before 2016, for example, don’t.

Emails going to spam

If we host your email, add an SPF record via Manage Domain → DNS Management in your Control Panel. Add this as a TXT record (you can only have one SPF record at a time, and only if we host your email):

v=spf1 include:secureserver.net exists:%{i}.mta.spf.extendcp.co.uk exists:%{i}.web.spf.extendcp.co.uk -all

Dealing with spam/junk mail

Spam happens to everyone, but there are filters in your control panel under Email → Junk Mail Filters:

  • One persistent sender? Add them under “reject by sender” and click Update.
  • Spam from lots of addresses? Adjust the Junk Mail Filter Level (Low/Medium/High/Extremely High). Go up one level at a time and check nothing genuine is getting caught.

PHP security update: what you need to know

A security issue affecting PHP (CVE-2026-109618 and CVE-2026-109619) affected a number of companies yesterday. Our hosting team has already patched PHP versions 7.2 and above across our platform against these specific vulnerabilities.

If your website is running PHP 7.2 or later, it’s already protected ✓ and no further action is needed.

If any of your websites are running a version below PHP 7.2, we’d recommend upgrading as soon as possible, provided your website is compatible — older PHP versions are no longer supported.

How to safely update your PHP version

Before you change anything: jumping up several PHP versions at once is a bigger change than it sounds, and you’ll need to make sure your WordPress site is compatible first. If WordPress, your theme, or any plugins aren’t compatible with the new version, parts of your site may stop working or show errors.

Step 1: Check your site is ready

1. Take a full backup of your website and database, so you can restore it if anything goes wrong.

2. Update WordPress, your theme, and all plugins to their latest versions — in your WordPress dashboard, go to Dashboard → Updates.

3. Check each plugin and your theme is compatible with the PHP version you’re moving to. Search for each plugin on wordpress.org — the plugin page shows the minimum PHP version it needs and when it was last updated. Plugins that haven’t been updated in a couple of years are the most likely to cause problems, so it’s worth replacing or removing those. For premium themes or plugins, check the developer’s website instead.

4. Check Site Health — in WordPress, go to Tools → Site Health, which will flag up any issues it finds.

Step 2: Change the PHP version

1. Log into your hosting account.

2. Click on Switch PHP Version.

3. Select the version you’d like from the drop-down list.

4. Click Update.

Once it’s changed, go through your website thoroughly — including the main pages, any forms, and the WordPress admin area — to make sure everything’s working as it should.

If something stops working

Don’t worry — you can switch back to your previous PHP version in the same place while you look into it. If the site has an issue, the usual way to find the cause is to deactivate all plugins, then reactivate them one at a time, checking the site after each one, until the problem plugin shows itself.

If you’re not sure about any of this, or would like us to check it for you, just get in touch.

Update, 22 October:

There’s been no evidence of this vulnerability being successfully exploited across our platform, and very little evidence of it happening anywhere else. Our default PHP configuration makes it difficult to abuse, but we’ll stay alert and take further action if anything changes.

SSL certificates

What is an SSL certificate? It keeps data secure between your website and its visitors’ browsers. Without one, browsers will flag your site as “Not Secure.”

Popular FAQs

Still have questions? Here are the answers to some of the most common questions people ask about Duport.

Company registration is the process you need to go through to officially set up a business. For Limited Companies, Non-Profits, LLPs and Charities, this is done through Companies House.

For Sole Traders, registration is done through HMRC.

The process is slightly different based on your structure, but Duport have a comprehensive service for each business type, so you can be confident your registration goes smoothly.

The best business structure depends on your own unique circumstances, and can change depending on a huge number of things, from how many people will be running the business, to whether you’ll be taking a salary.

If you’re not sure what structure is right for you, our Quiz can make it all clear!

Just answer a few easy questions, and we can help you decide which business structure is going to be right for you - as well as the best package of services to suit your needs.

You’ll even get a free Start-Up Report that explains each recommendation, and why it will work best for you.

The Start-Up Report is a full breakdown of your business needs, to help you decide what company structure and services will work best for you.

This Report helps you decide whether you should be a Sole Trader or Limited Company, whether you should register for VAT, if it’s worth getting a Registered Office Address service and much, much more.

While the vast majority of our customers find it quick, easy and efficient to set up online, we appreciate it can feel daunting.

If you’d rather talk to one of our expert advisors instead, please just give us a call on 0117 950 2667. We’re available Monday to Friday 09:00-17:00 and we’ll be more than happy to help.
