Uniweb and Zendesk integration

Uniweb is commonly deployed alongside Zendesk, appearing in the mail stack of smaller organisations that use Zendesk for helpdesk and customer support. This coupling means that senders targeting such sites may encounter Uniweb as the mail endpoint for support emails, ticketing confirmations, and customer-facing correspondence rather than as a primary corporate mail provider.
