By default, all Secure Mail generated web traffic is processed with Secure Web.
If you prefer to split those web traffic between Secure Web and native browser, you may create a list of URLs (typically, internal domains) via configuring an MDX policy in the Citrix Endpoint Management console called "Allowed Secure Web Domains". More details referring (https://docs.citrix.com/en-us/citrix-secure-mail/iOS-android-features.html#allow-secure-web-domains-mdx-policy-for-secure-mail)
