SmartMail — webmail client for a hosting provider

What it is

A mail application for staff of a hosting and datacentre company, talking to the organisation’s own SMTP/IMAP infrastructure rather than a third-party provider.

What it involved

A clean Gmail-style interface with light and dark themes, several signed-in accounts at once with fast switching, and session handling that quietly refreshes an expiring access token in the background instead of dumping the user back at the login screen — the kind of detail that decides whether people keep using an internal tool.

Why it matters for your project

Integrating with infrastructure you already run, and getting authentication right, is most of the work in a real business app.
