Alternate Ways of Sending Emails

Emails can be sent from OneSpan Sign in three alternate ways:

The Custom SMTP Server and DKIM Signing methods both enable the From field to be configured with the customer's email address when emails are sent.

Using OneSpan Sign's Email Server

This is the default method. It requires no changes to your account.

Using a Custom SMTP Server

If a Custom SMTP Server is used, all email bounce-backs must be handled by the customer.

To ensure email delivery is successful using SMTP, you must authorize OneSpan Sign to communicate with your mail server. Depending on your configuration, IP whitelisting may be required. For information about whitelisting IP addresses, see Environment URLs & IP Addresses.

If you are using any mail service other than Microsoft Exchange 365

If you are using any mail service other than Microsoft Exchange 365 you must specify the following information:

Username

If you are using Microsoft Exchange 365

Using OneSpan Sign's Email Server with DomainKeys Identified Mail Signing (DKIM)

This method supports both DKIM and SPF authentication. Unlike the Custom SMTP Server method, this approach doesn't require the creation of a special server account for OneSpan Sign. However, additional fees apply; for details, please contact your Professional Services Consultant.

IP addresses must be whitelisted. For information about whitelisting IP addresses, see Environment URLs & IP Addresses.
