Spam, Spam with Eggs, Potato Spam de luxe. And Spam.

Original title: "once junk, always junk..."

[I'm not sure how many bugs, issues and feature I found. Have fun! ;-] [reordered to make more linear sense out of it. Frankly, I found several patterns, but there seem to be several overlapping issues, both bugs and features] [May be best to try yourself and ask me and yourself specific questions]

1. Some 'unjunked' mails are still in the 'Junk' Mailbox.
   The junk feature is assigned correctly.

Ok, just found the 'Move to/from Junk' options - only available for '+junk' mails. I guess that's to check back on suspect mails which is marked as '-junk'.

But that option appears only sometimes... ok, seems I'm allowed to move '+junk' mails out of the junk. And '+junk' mail which is not in the folder can be moved there. Makes sense.

1. I first took the 'Junk' folder on a par with 'Flagged', i.e. a smart folder for the feature '+-junk'. But it's a aggregator for the different 'Junk' folders.

• Later: Now I've tagged the correct Google folder as 'Junk'. But the 'Junk' mailbox still does not contain any mail.
• Ok, that worked after a restart.

So, the '+-junk' flag is separate from the folders.
* Assigning the flag doesn't always work, i.e. shortcut and menu click do not always work - (may be due to reload of folders?)

1. Btw, I changed the shortcuts (PP Keyboard). The Junk State/Junk shortcut works for both 'Junk' and 'Not Junk', Junk State/Not Junk only for 'Not junk'.
   
2. At the moment, you can't toggle 'junk' by shortcut because it's two separate entries in the menu.

3. Well, toggle works with the Junk Status/Junk shortcut, which makes Junk Status/Not Junk superfluous.

4. The toolbar buttons are for 'move to', despite the simple label 'Junk'.

5. And for 'move from', I just found out.

6. In Junk mailbox I try to flag mails as 'Junk', but that doesn't work for all
   (mh, MM likes V!agra mails - more seriously: *ok, found the pattern - well, linguistics training 'pays' after all: 'This message is marked as junk' and 'This message is not marked as junk' are only displayed when some 'external reference' is blocked.

7. YES, the block holds for mails manually marked as 'not junk' - I expected automatic loading of the 'references'.

8. This may subsume: And I had some 'unjunked' mails which are in another folder but whose 'external references' are still blocked. Can't say when exactly.

Btw, some related stuff:
Is there a way (yet) to opt out of Mailmate's automatic junk marking?
And the 'Spam' value is always 0.00. Is it active at all?

Btw, you are fast!
