A couple of years ago I fell out with #gmail and migrated to https://privateemail.com
I've now fallen out with privateemail and decided to selfhost (again).
Now running #postfix, #dovecot, #rspamd and others via docker-mailserver. Had to use #smtp2go for outbound due to relay issues.
Also selfhosting #radicale for calendar/contacts and #immich for photos.
So far so good ... seems faster than I had before plus #opensource. Need to let it bed in a bit and keep an eye out for errors.
