I want to move IMAP to my VPS and move CalDAV and CardDav to the same VPS or possibly the homeserver.
A fortunate plus-side will be that my email address the same as my XMPP address.
If I ever get tired of self hosting or find it too inconvenient. I will just point the MX records of my domain at a new email host.
Decide if I need a backup email provider. ( Example: Maybe a day will come when I will need to email the VPS support, while my VPS is down? )
Setup mailservices on VPS. Possibly redoo the whole OS while we are at it. Setup MX records. Etc.
Test email functionality. Possibly against a bunch of email hosts among family and friends. Make sure my smtp server isn’t being flagged as dangerous and other claptrap.
- Local public library has issues with posteo.net. Specifically because of how their name resolution is setup on their domain. It’s extra peculiar. This should be tested.
Migrate all various accounts that refrence the old address to the new.
- Criticial accounts such as the VPS might need to be associated with the backup provider. If I decide I need one.
Backup Calendar, Contacts, E-Mail folders migrate them to the new.
Setup backup schedule for email via BorgBackup.
Consider if I want to revise my current policy of not using GnuPG
