[MlMt] Rules: "is in" smart mailbox and Gmail Labels

[Zvi Biener]

Hi Folks,
There has been lots of discussion of rules lately, so I apologize if 
this was already addressed:

I'm having trouble setting rules, under the following conditions:

1. I use Gmail labels by hiding the associated gmail "mailboxes" from 
MailMate (through the "Edit Subscriptions"). I then use Smart Mailboxes 
that pick out messages with the appropriate labels. So, if I use Label 
"Marketing", I hide the Marketing mailbox from MM, and define a smart 
mailboxes that picks out all messages with the tag "Marketing" from All 
Messages. I do this so I don't have duplicate messages, and because I 
use the same tags/keywords across multiple accounts.

2. I'd like to define a rule that matches the from address of incoming 
mail against from addresses that are already in the "Marketing" smart 
mailbox. Like: "From -> Address" "is in" "Marketing" (the smart mailbox) 
"From->Address".
However, in this context mailboxes that are defined as in 1 are greyed 
out. Other smart mailboxes are OK, but any smart mailbox that picks out 
a gmail label is greyed out.

Any ideas on how to get around this?

Thanks,
Zvi
