My guess is that they are in the Trash folder too. Alternatively, the 
Trash folder in Postbox is a local offline mailbox.

When Postbox moves a message then it actually copies it and marks the 
original for deletion (this is how IMAP works). The problem is that 
Postbox might not commit the deletion until later, e.g., when changing 
the currently selected mailbox (the exact behavior varies between email 
clients). The commit is known as EXPUNGE in IMAP language.

For the record, MailMate expunges immediately after marking a message as 
deleted. MailMate is also very careful not to expunge messages marked as 
deleted by other email clients. Most of the time though, it should be 
safe to delete messages with a red dot.
