A fully self-hosted, Free Software, standards-compliant email service.
Using your Account
As with most of our services, this uses our accounts system. Your email address is your username at the group’s domain.
We publish autodiscover details for the below, but you might need to enter the details manually if your client doesn’t support autodiscovery.
For all protocols, TLS is required (the server will not accept passwords sent over plain-text). It’s important that outgoing emails go via our SMTP server as we publish DKIM and SPF records.
We use letsencrypt as our certificate authoraty and use DNSSEC for our DNS records.
You may want to use filters to help organise your email. Our email service supports a powerful email filtering language called sieve which allows you to script your filters. Some clients natively support sieve, while others such as thunderbird have extentions.
Email address aliases are supported, but creating them is a manual process, let the admins know if you would like an alias and they will create it for you.
Some email addresses are set up as forwarding groups (security alerts, admins, etc…). If you would like to be included in these emails then let the admins know.
Some of our services need the ability to send email, we have dedicated accounts for this purpose. If you require one let the admins know. Don’t use your personal account for sending automated service emails.
Here are some tips for using the service.
The server should be set-up to support address extentions, this allows you to include a + followed by a optional part to help you sort your email, for example firstname.lastname@example.org would be delivered to your inbox. You can use seive to filter these messages based on the ‘to’ address.
Although we use TLS for communications with the server, you may wish to make use of PGP as another layer of security. Using PGP allows you to send end-to-end encrypted emails. To make effective use of this, both you and the other party will need to setup and use PGP. We recommend using the keys.openpgp.org to publish your public keys.
