![]() Hence, you need to keep track of the changes and keep updating the list. The problem is, since the IP addresses under your SPF record may change (because Google Workspace scales the servers up and down according to the demand at a particular point), in case there are a few IP addresses that haven’t yet been entered in your outbound mail gateway server account, the emails originating from these IP addresses will be stopped, even the legitimate ones. If the IP address from where the email is coming does not already exist at the outbound mail gateway server list of approved IP addresses, the email will not be allowed to go further. This way the spammers won’t be able to use your gateway for open email relay. You have to manually enter all the Google Workspace mail server IP addresses that should be allowed to relay email messages. These are white-listed server IP addresses. Most of the outbound mail gateway servers need you to supply a list of approved IP addresses through which email messages can be accepted. You can set up rules in your email outbound gateway service to process email messages before they are delivered so that messages carrying certain attachments and bits of information are not allowed to pass through. Such an attack, if left unchecked, can cause irreparable damage to your business and brand. You may want to set up an outbound gateway server with your Google Workspace account to route all outgoing messages from your domain for the purpose of spam filtering or archiving.Īn external email outbound gateway gives you more control over what types of messages are allowed to go to your recipients from your domain so that if a spam or a phishing attack is attempted using your domain, it can be stopped before it passes through the external email outbound gateway. An example of why you would need to access and track a list of Google Workspace mail server IP addresses Suppose you’re using an external email outbound gateway.Why do you need to track Google Workspace IP addresses ?Īn example of why you would need to access and track a list of Google Workspace mail server IP addresses For such a case scenario, it is advisable that you have a system of tracking your Google Workspace mail server IP addresses in cases where instead of using SPF, you are relying on the list of Google Workspace block IP addresses. It doesn’t happen often but if and when it does, it may stop certain emails from reaching destination in boxes. Hence, even if you have a list of the Google Workspace mail server IP addresses, sometimes a list may change. As mentioned above, these servers are randomly picked according to the demand. There is no definitive list of your Google Workspace mail server IP addresses. You can watch my video guide on Google Workspace SPF record for better understanding. This way your recipient email servers can check if the email came from your authorized email server or not. ![]() You do this by adding an SPF record to your domain SPF stands for “Sender Policy Framework”, to summarize, this is the way for you to tell your recipient email servers about the email servers you authorize to send emails on your behalf. When you send emails to your customers, clients and business partners, their email clients, they want to make sure that the email is actually coming from you and not from a spammer. When using Google Workspace, you need to set up an email account (or multiple email accounts according to the needs of your organization or business) for your domain. The same is the case with Google Workspace. Since these email servers are randomly chosen to handle email traffic, your emails need to interact with multiple IP addresses on different occasions. Email servers are used to handle incoming and outgoing traffic.Įvery email server has a unique IP address. To handle this massive traffic, Google maintains a global infrastructure that scales dynamically as per the demand. So, you can very well understand the quantity of incoming and outgoing emails the Gmail servers, that are basically the backbone of Google Workspace email servers, must have to handle on a daily basis. ![]() Gmail has over 1.5 billion active users worldwide, according to Statista. ![]() In 2019, more than 293 billion emails are being sent worldwide every day, and the figure is projected to grow to 347 billion by the end of 2023 (source). You can either do it manually by running DNS lookup commands, or you can use a Google Sheets tool described here. In this blog post you will learn how to access and track the IP addresses of the Google Workspace mail servers. How to keep track of Google Workspace mail server IP addresses ![]()
