Configuring Mail Server

You can configure Remote Access Plus server to automatically notify you via e-mails on various important events. Follow the below steps to configure your third-party mail service such as Google Apps to send you e-mail notifications. Mail Server Settings can be configured in two ways:

OAuth Authentication

OAuth is a standard authorization protocol that uses web tokens instead of passwords to allow delegated access to a protected resource. OAuth allows limited access to the users data, that is, the ability to share data for users without disclosing personal information. Therefore, we can choose to configure using OAuth authentication for sending mails from Remote Access Plus server securely.

Frequently Asked Questions

Why should I move to OAuth2.0?

Google and Microsoft will soon withdraw basic authentication support for mail servers by 30 May 2022 and 1 October 2022, respectively. Therefore, it is advisable for users to switch to OAuth authentication.

What are the supported mail servers in OAuth?

We have tested OAuth authentication with Microsoft Outlook(office365) and Gmail(Gsuite).

Can I configure OAuth for an existing mail account?

Yes. You can configure OAuth for an existing account.

What is Redirect URL and where should I configure it?

Redirect URL or Reply URL is the URL to which the Authorization Server sends confidential response data. Copy-paste the Redirect URL to the application details in the Authorization Server and save it.

On clicking Save, I am getting an error stating "Redirect URL or reply URL invalid/mismatch". What should I do?

Check if you have added the application server's redirect URL to your authorization server's list of redirect URLs. Ensure that you have saved the settings.

What will happen if my access token expires?

When your access token gets expired, a new access token will be automatically generated using the refresh token.
