Configure SMTP Server Settings

Strato Administrators can configure their email sending options using the SMTP Server Settings section in the Strato Admin Tool.

Simple Mail Transfer Protocol (SMTP) simplifies the communication of email messages between email servers. User-level client mail applications like Strato's email feature use SMTP mainly to send emails, not to receive them.

This article provides an overview of configuring the SMTP Server Settings section in the Strato Admin Tool.


Instructions

To configure your SMTP settings, you must first select the Type of authentication between Basic or Bearer. After you have selected the authentication type, you must complete the information for the respective fields.

Clients who prefer to use their own SMTP server for sending emails should provide their server details to configure the SMTP settings.

By default, only Basic authorization is available. To enable Bearer authorization, you must first install the Security Enhancement - oAuth Enablement for SMTP services in the Upgrade Center.


For Basic authentication, here are the fields you must complete:

FieldDescription
*Hostname / *Username / *PasswordThese are based on your email configuration. You may ask your local IT team about your settings.
*PortThe port used for SMTP. The default SMTP port is 25, unless you have a different one depending on your requirements and ISP.
*Sender email addressThis will be the default sender for all of your Strato emails. As this is an SMTP server configuration, Strato can only send emails and cannot receive them. Ensure that it is clear to your recipients that the mailbox you are using to send your communication cannot receive emails. A different option should be provided to them should they want to respond to your email.
Send using TLS

It is recommended to enable this for the server to send emails securely. When enabled, sent emails will be encrypted using Transport Layer Security (TLS).

If the port is set to 587, then Send using TLS should be toggled On. If it is port 25, then Send using TLS should be toggled off.

Fields with * are required.


For Bearer authentication, here are the fields you must complete:
