Unable to send 530 Relaying not allowed

When trying to send an email you may receive a message of "530 Relaying not allowed"

This error means that you are trying to send an email without sending your login to the email server first, you are required to send your login first otherwise anyone could connect to our servers and send email on your behalf.

This is a very common mistake when setting up your email accounts in your email program or mobile device etc.

The information you need varies depending on your choice of operating system.

Please read the relevant Apple or Windows section below.

Apple Users

If your device is an Apple device so iMac, iPhone, iPad etc then during the setup of your email account Apple for reasons known only to them decided that when you are entering your settings and get to the outgoing server settings that they would place the word "Optional" in the username and password boxes.

So naturally a lot of people think the username and password is.. well optional! but it is actually mandatory so please do ignore that and enter your email account username and password also in the outgoing server username and password boxes.

Now if you have already added the account you will have to navigate your settings and enter the outgoing username and password in to resolve this problem.

However more often it is easier to remove the email account and re-add it again from scratch, just make sure you have a backup of any emails before you do so.

Windows Users

For Windows users you need to edit your specific email account settings and have your mail program send the username and password for outgoing mails also.

There are quite a few email programs for Windows but the most common is Outlook so I will explain how to find the setting within Outlook and this will give you a heads up regarding what to look for if your not using Outlook when consulting the documentation for your chosen email client.

In the newer versions of Outlook 2013 onwards you click "File" then "Account Settings" then the click little "Add and remove accounts or change existing connection settings" that appears.

In versions of Outlook prior to 2013 you click "Tools" then "Accounts"

Next regardless of your Outlook version you should now see a window with your E-mail accounts listed in it.

Highlight the email account you are having problems with by left clicking it once and then click "Change"

On the next window that appears you will see your account settings, the part we need is in the bottom right called "More Settings" so click that.

You will now get another window and in this there are several tabs to choose from, one of them is called Outgoing Server, click it.

We are now where we need to be to sort this out, first put a tick in "My outgoing server (SMTP) requires authentication"

Now check that "Use same settings as my incoming mail server" is selected (it should be by default) and click "OK" which will close that window.

On the next window click "Next" and depending on your settings this may trigger a test of your account settings, if it does let it run and once done click "Close" then click "Finish" and then finally click "Close" again on the final window. (depending on your settings these may slightly differ but if you work your way back out if it differs!)

Now try sending an email and all being well it should send!
