A rather large caevat on Maddy: *Note: IMAP storage is "beta". If you are lookin...

Yeah it's "beta", but I've been using it for years at this point.

That warning has been there for a while -- I don't think it's accurate at this point -- You can use SQLite or other DBs to hold your IMAP data:

https://maddy.email/reference/blob/fs/

https://maddy.email/reference/blob/s3/

I've used all three of these actually (over the years -- more recently I've moved a bunch of my imapsql workload to S3-compatible storage on Backblaze) and they work great.

If you're sending and receiving gobs and gobs of email maybe think twice, but for someone who is dipping their toes into self-hosting email maddy is one of the best choices out there.

As usual YMMV, and back things up, if they are important to you.
