Mailboxes are always full
…as most hosting providers only offer a few hundred megabytes to their clients. Delete old messages? You must be joking – there are scaling clouds all over us!
Why does nobody provide infinite, pay-what-you-use mailboxes?
Use gmail, with cheap Google Drive storage! But then i can't use my own domain…
So should i run my own mail server?
Have it hosted
There is a choice of big mailboxes (ordered by storage space and price)
- Google Apps unlimited storage; 8€/month
- Domain Factory Managed Exchange unlimited storage; 13€/month
- Fastmail 150GB per box; 315$/year (~26$/month)
- Rackspace Hosted Exchange 100GB per box; 10$/month
- Rackspace Email Hosting 25GB per box; 2$/month; requires ordering at least 5 boxes
- Zoho Mail 25GB per box; 10$/month
Host it yourself
These are tools that help you set up a mailserver in very little time with very little knowledge or skill required.
Modoboa and Mail-In-A-Box are the ones i've tried. The former sets up your mail service and hands you a nice django-frontend for managing it. It is extensible via plugins and seems overall very well-made and highly adaptable.
Mail-In-A-Box offers far less configuration options that Modoboa, but goes into another direction. You run it on a fresh Ubuntu 14.04 and it takes care of everything, including firewall, dns and ssl setup. To me it seems by far the quickest and simplest solution to a production-ready mail server.
