Emails tend to leak easily. I keep a server to track such leaks, one email per service. I'm using Modoboa, but it is limited due to its complexity. I'm not sure I can reinstall it with certificates, backups and more being OK.

• Hosting providers are bokers and block the email-related ports on the VDS servers
• The general complexity of email stack prevent you from having extensive control and making backups
• I wish more people were responsible for their own security, as that'll lead to a mutual benefit
• First, I have doubts on Postwhite's architecture and want to rewrite it
