Nextups
- Support sending emails - Also support for popular services like mailgun/sendgrid
- Smart assistant like functionality. For e.g.
- You don't need all emails of package deliver status. Just the latest one would be enough.
- Some type of emails can auto expire. Old newsletters are not very helpful
- Aggregate emails for weekend reading.
- Small webserver
- SPAM filtering - not that important as you can use unique addresses for each service. e.g. facebook@mydomian.com, bankac@mydomain.com, reddit@mydomain.com etc. You can easily figure out who sold your address to spammers and block it.
Goals
- Intended to be used for one person. So won't have features that don't make sense in this context. e.g. LDAP AUTH, Mail quota, etc,
- Supports only python3.7. No plans to support older versions
Known to work
- Server: Google Cloud f1-micro with Ubuntu 18.04 - Always Free instance
- Clients: thunderbird, evolution, k9mail
- smtp: Received email from all. Didn't see any drops. Tested from gmail, protonmail, reddit and few others
