Allowing external senders to email sub-domain addresses in Exchange Server 2019

I am not very familiar with Exchange, but I would like to know how to allow external senders to email our sub-domain email addresses. We are using Exchange Server 2019 on-premises, and we have a sub-domain email address ******@intr.xyz.com which is currently only accessible by internal users using foreign connectors. External users are unable to send emails to this address. Can someone please guide me on how to set this up? Thank you.

    Hello Kuldeep,

    There doesn't seem to be many articles on this. roughly similar to : Enable mail flow for subdomains

    generally, just to add an authoritative domain and the corresponding public network MX record.

    Just to confirm, what "foreign connector" refers to? the actual incoming server not owned by your organization?

    If so, then the accepted domain needs to be added with internal relay.

    Regards
