• Microsoft Account Creation: Microsoft Account Signup

Setting Up SMTP AUTH Client Submission

Once you meet the requirements, follow these steps to set up the SMTP relay in your CRM.COM application.

Configure Settings in CRM.COM

Enter the following settings directly into the CRM.COM application as instructed. Based on SMTP AUTH client submission, these settings will allow you to send emails from the CRM.COM application.

 Features of SMTP AUTH client submission

• SMTP AUTH client submission allows you to email people in your organisation and outside your company.

• This method bypasses most spam checks for emails sent to people in your organisation. This bypass can help protect your company’s IP addresses from being blocked by a spam list.

• With this method, you can send email from any location or IP address, including your (on-premises) organisation's network or a third-party cloud hosting service.

Requirements for SMTP AUTH client submission

• Mailbox: You must have a licensed Microsoft 365 or Office 365 mailbox to send email from.

• Transport Layer Security (TLS): Your device must be able to use TLS version 1.2 and above.

• Port: Port 587 (recommended) or port 25 is required and must be unblocked on your network. Some network firewalls or ISPs block ports, especially port 25, because that's the port that email servers use to send mail.

• DNS: Use the DNS name smtp.office365.com. Do not use an IP address for the Microsoft 365 or Office 365 server, as IP Addresses are not supported.

Conclusion: SMTP relay through Microsoft 365 or Office 365 provides a reliable and efficient method for sending emails from your CRM.COM application. By accurately configuring the settings outlined in this guide, you should be able to send emails to your contacts seamlessly. You can confidently expect successful email delivery and communication through Microsoft's robust email infrastructure if the settings are correct and properly aligned. Always ensure the accuracy of your settings to ensure smooth email delivery and prevent any potential issues.
