What is the recommended email server configuration for HumHub on Linode?

The recommended email server configuration for HumHub on Linode will depend on your specific needs and preferences. However, to ensure reliable email delivery, you can consider setting up the following components:

  1. SMTP Server: Install and configure a reliable SMTP server software like Postfix or Exim. These servers handle outbound email delivery, ensuring that emails sent from your HumHub installation reach the recipients' inbox.
  2. SPF and DKIM: Implement Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) to authenticate your outgoing emails. These mechanisms prevent email spoofing and ensure legitimate delivery.
  3. Reverse DNS: Set up a reverse DNS (rDNS) entry for your Linode's IP address. This step helps validate your domain's identity and avoids being flagged as spam by the receiving servers.
  4. DNS Configuration: Properly configure your domain's DNS records, including A, MX, SPF, and DKIM records, to ensure accurate email routing.
  5. SSL/TLS Certificates: Obtain and install SSL/TLS certificates for your email server to encrypt the communication between your server and other mail servers.
  6. Monitoring and Logging: Set up monitoring and logging tools to track the email delivery process and promptly address any potential issues or failures.

It's crucial to consider the specific email deliverability requirements of your HumHub installation and consult relevant documentation while configuring your email server on Linode.
