Create your mail server for free in less than 10 minutes with Modoboa
When it comes to create a mailbox, you generally have several solutions:
- Use the services offered by Internet providers (Orange, Vodafone...) of infrastructure providers (OVH, Gandi...) with a monthly or annual subscription. However, customization and configuration possibilities, domains and mailboxes number are limited.
- Use the services of free email providers (Gmail, Live, Yahoo...) which are limited and your data is used for commercial purposes.
- Install your own email server, which requires important technical knowledge to setup and configure the system.
Modoboa is an alternative to those 3 options. It frees you from dependence on email providers and makes accessible to all the creation his own secure email server. The whole thing, in less than 10 minutes and freely.
