Simple Mail Transfer Protocol (SMTP) credentials are needed to send email through Email Delivery.
The SMTP credentials are used for SMTP authentication with the service. The credentials never expire.
A user can have up to 2 SMTP credentials at a time.
Note:** The credential set is always an Oracle-generated SMTP user name and password pair;
you cannot designate the SMTP user name or the SMTP password.
For more information, see [Managing User Credentials](https://docs.us-phoenix-1.oraclecloud.com/Content/Identity/Tasks/managingcredentials.htm#SMTP).
Note: Objects should always be created or deserialized using the
Builder. This model distinguishes fields
that are
null because they are unset from fields that are explicitly set to
null. This is done in
the setter methods of the
Builder, which maintain a set of all explicitly set fields called
#__explicitlySet__. The
#hashCode() and
#equals(Object) methods are implemented to take
#__explicitlySet__ into account. The constructor, on the other hand, does not set
#__explicitlySet__(since the constructor cannot distinguish explicit
null from unset
null).
