(as a reply to your mail) I'm not subscribed to the mailing list, but I just read your thread regarding this plugin.
It seems to me that the Shift-Delete function you are referring to in Thunderbird just bypasses the built-in move-to-trash-on-delete function, but on the server-side is identical to any other regular delete action (flag the message as deleted, followed by an expunge later on, probably after closing the mail client) and is thus copied to the trash folder by my plugin. I can't think of anything to distinguish this behavior from a normal delete action by any other mail client and using Shift-Delete in Thunderbird (server-side), if you know one, please let me know and I will try to implement it. Greetings, Lex Brugman
