Email Management

Hypha members are eligible for Hypha email addresses, such as joe@hypha.earth. Hypha does not provide full email support, so we suggest to forward messages from your Hypha account to your personal email account (e.g. at Gmail) as soon as you have access. 

The guide is incomplete as of 9/20/21. Following activities need to be performed:

1 Define new role for Email Management
2 Clear our unused mailboxes (purge and/or delete)
3 Enable forwarding for ALL remaining mailboxes
4 Improve on Mail server status

Introduction

Cloudron has a built-in mail server that can send and receive email on behalf of users and applications. By default, most of it's functionality is disabled and it only sends out mails on behalf of apps (for example, password reset and notification emails). Hypha has enabled Cloudron Email and offers a full-fledged mail server solution. Each user can get a mailbox username@hypha.earth and can send mails using SMTP and receive mails using IMAP. Admins can also setup server side mail filtering rules using ManageSieve.

Features of this mail solution include:

  • Multi-domain support
  • Enable mailboxes for users and groups on a domain level
  • Per-user and group mail aliases (via mailboxes)
  • Mailbox sharing amongst users
  • Group email addresses that forward email to it's members
  • Email account sub-addressing by adding + tag qualifier
  • Setup mail filters and vacation email using ManageSieve
  • Catch all mailbox to receive mail sent to a non-existent mailbox
  • Relay all outbound mails via SendGrid, Postmark, Mailgun, AWS SES or a Smart host
  • Anti-spam. Users can train the spam filter by marking mails as spam. Built-in rDNS and zen spamhaus lookup. Admins can add custom spam rules for the entire server.
  • Completely automated DNS setup. MX, SPF, DKIM, DMARC are setup automatically
  • Let's Encrypt integration for mail endpoints
  • Domains and IP addresses blacklisting
  • Server-side mail signatures (can be set per domain)
  • REST API to add users and groups
  • Secure out of the box
  • Full text search using Solr
  • Event Log
