## Path Parameters

## Body Parameters

string

default:"opportunistic"

- `opportunistic`: Opportunistic TLS means that it always attempts to make a secure connection to the receiving mail server. If it can’t establish a secure connection, it sends the message unencrypted.
- `enforced`: Enforced TLS on the other hand, requires that the email communication must use TLS no matter what. If the receiving server does not support TLS, the email will not be sent.

object

Update the domain capabilities for sending and receiving emails. You can specify one or both fields. Omitted fields will keep their current value. At least one capability must remain enabled.

:::accordion{title="Show properties"}
string

Enable or disable sending emails from this domain. Possible values: `'enabled' | 'disabled'`

string

Enable or disable receiving emails to this domain. Possible values: `'enabled' | 'disabled'`
