One email server for every one of your domain names.
The LinuxBusiness Email Server handles email for all of your domain names from one place: ceo@, sales@, support@ and the rest, for every company and brand you run. Addresses forward where you want them, every domain has its own security certificate, and a clear window shows what arrived, what was sent and what was turned away.
It can run on LinuxBusiness's servers, so there is nothing for you to look after, or on your own machine, so your mail never leaves your building.
Business Email, in short.
Every domain, one server
Add a new domain name in minutes instead of setting up another mail system.
Addresses that forward
Any address can deliver to one inbox or several, across domains.
Secure mail
Encrypted connections, a certificate for each domain, and sender checks that help your mail land in the inbox, not the spam folder.
Spam and abuse kept out
Unwanted senders are turned away before their mail reaches you.
Your choice of home
Hosted on LinuxBusiness's servers, or on your own machine.
