I just did a search through my archives - seems this topic has been requested a few times since my posting two years ago. I asked about a specific implementation - which Mr. Sirainen never commented on. He was probably focused on something more important at the time - like a paying job. So I'll ask again...
Calling Timo!
If we can't get clients to agree on a "standard" set of folders (probably reasonably safe assumption) and if protocol implementations of variations of "*LIST*" are too far in the future...what about having alternative folder names presented based on login name - maybe by an extension? So where my usual login might be "user@domain.com", and that would continue to be supported as the default login, I could now have "user@domain.com+thunderbird", "user@domain.com+mobile", etc.?
And each of those extensions would then have a system-wide map defining folder name relationships, like "Sent=Sent Items". Does this seem doable?
