Slightly off-topic, but I have MM configured for "true" IMAP style delete and expunge semantics.  First, I have these settings configured:

% defaults write com.freron.MailMate MmShowDeletedMessages -bool YES
% defaults write com.freron.MailMate MmDeleteBehavior -string "markAsDeleted"

In addition, I have the following custom keybindings configured in my ~/Library/Application Support/MailMate/resources/KeyBindings/Delete.plist file (you need to enable custom keybindings file(s) in the General tab of MM's preferences):
{
        "d" = ( "setTag:", "\\Deleted", "setTag:", "\\Seen", "nextMessage:" );
        "u" = ( "removeTag:", "\\Deleted" );
        "\U007F" = ( "setTag:", "\\Deleted", "setTag:", "\\Seen", "nextMessage:" );
        "x" = "expungeDeletedMessages:";
}

So the 'd' or 'delete' key will do the IMAP style delete operation (the message remains visible, with a cute little trashcan icon), and 'x' will expunge any such deleted messages in the currently selected mailbox folder.

Finally, I added the "Delete" and "Expunge" icons to my toolbar, which work as expected with my other settings.

I forgot where I learned all this (it's been working this way for years); I don't see it in the Hidden Preferences section of MM's Help->MailMate Help menu.
