Thanks! Your solution may be best for usability. Researching further I found another solution that is perhaps best for privacy: https://github.com/markushinz/aws-ses-pop3-server

SES -> S3 -> aws-ses-pop3-server -> desktop client with POP3 and SMTP

Using this option, email is only really usable from a single device, but it avoids sharing private emails with yet another cloud, especially a free cloud that would share email with advertisers.

EDIT: Wanting a minimal implementation, I instead made a script:

1. List email files in S3

2. For each file, download into a local maildir-style directory, then delete original

3. Use `mutt -f ./maildir` to browse

Hmm you could probably use the AWS CLI's "aws s3 sync" command for that right? Sounds pretty practical

You can probably make that work, just have to be careful deleting from S3, make sure to only delete those emails you imported and not accidentally delete an email that arrived during the import process.

My personal setup makes heavy use of rclone so I used that instead of awscli:
