Alexey Melnikov answers Ned Freed:
Indeed. I don't believe I've ever seen a publicly available client capable of it either.Polymer can do that, even though it is hardly a mainstream client.I am trying to remember (from the Lemonade interop event) if there was one more client.
There wasn't.I've (once) seen server log entries that showed either BURL/CHUNKING or IMAP CATENATE in the wild, can't remember which. No idea what client.
One swallow does not a summer make. Arnt
