Is there a modern Windows software like IMAPSize, an open source (formerly freeware) program, that can modify or at least upload IMAP messages? While IMAPSize still works, being abandonedware it carries noticeable issues, like:
- It can't edit messages, only upload new ones. I can live with that, but:
- It doesn't care which date stamps the messages have, instead opting to upload them as new. I.e. doesn't have support for sending the parameter which PHP describes as internal_date.
- It only supports username/password and not OAuth, which is both insecure and blocked by default in places like Gmail.
A webapp service is acceptable too.
