I want to setup a local email server that works on a LAN/WLAN only.
Basically I have a server that sends emergency alerts via email currently. These events are being sent currently to a iCloud email address. iPhones onsite will receive the email via push notifications for staff to respond. The issue is that it relies on 3rd party services (internet, push cloud services etc.)
Is there away to setup a internal local email server with push capabilities? This way the iPhone just need to be connected to the WLAN (same lan as the mail server) to get interna emails.
Apologies if I’m not explaining what I’m looking for good enough !
