Do Ivertec provide an SMTP server to customers?

As of January 2019, Ivertec no longer provide an SMTP server to customers. SMTP servers (using Port 25) are becoming a common target for email spammers, so it is now best practice for Internet Providers to discontinue providing an SMTP server while also blocking traffic on Port 25.

Larger operators, including Vodafone, have recently shut down their SMTP server in line with this new industry security standard.

For Residential Customers

Can I continue sending emails? Yes, you can continue to send emails through your email provider’s website, E.g. Eircom Web Mail. Simply visit the website and enter your username and password to log in.

We understand that you may wish to continue using the email apps on your PC and smart phone, e.g. Microsoft Outlook, Apple Mail, etc. To avoid disruption to your outgoing mail on these devices, you will need to change to an alternative SMTP server and enter new settings on your devices.

If your using an Eircom, AOL, or IOL email account, please note that these operators may not offer a secure STMP server. We recommend that you create or use an existing Gmail account and link it to your email address. Click here for instructions. Additionally, you will need to insert Gmail’s IMAP and SMTP settings to your email client on all your devices. Click here for instructions.

If you currently use Gmail, you only need to change the outgoing port to 587. This applies to any email provider who offer port 587.

For Business Customers (using their own domain name e.g.

 If your email address matches the name of your website or business, e.g., we recommend that you contact your web hosting provider, e.g. Register365, and request new SMTP settings.

Alternatively, you can use a third-party SMTP service such as Sendgrid, AuthSMTP or Socketlabs.

You must use an authenticated SMTP service that uses ports other than Port 25 (e.g. 587). Port 25 is blocked by Ivertec.

Do Ivertec block Ports?

Ivertec do block traffic on port 25.

If you need to open ports on your connection for certain applications then you can do so by changing the settings on your Wi-Fi router.

My IP Address

Ivertec provides you with a Dynamic (DHCP) IP Address. This means that it may change but does not affect your service.

If you require a Static/Public IP Address then we can provide you with one. We will send you an SMS containing your unique Static/Public IP Address. If you have forgotten your IP Address, you can locate it by Googling “What’s my IP address?”

NAT Type

Ivertec operates using a NAT’d network. This is common for internet service providers due to the shortage of Public IPV4 addresses in the world and will soon change once IPV6 is more prevalent.

A NAT’d network means sever IP addresses are all working off one Publicly Visible IP address. This doesn’t affect your internet connection or how you view content.

This can however be an issue for online gamers. When running a network connection check on your console it may say you have a NAT Type 3 which will prevent you from hosting games or accessing certain content for online play.

Give our office a call or send us an email and we can provide you with a Static/Public IP address to allow you receive a NAT Type 2 connection.
