[MlMt] "Apply rules" — do anything?

[David Pesetsky]

I am trying MailMate (which I tried once a decade ago) with an eye to a possible switch from Apple Mail — one of the reasons being problems moving messages around in my work Exchange account that finally caused me to turn off Rules in that app, leaving a lot of old messages not filed where I want them.

MailMate using Exchange's IMAP server seems to have no problem moving messages manually, but when I try to use newly created rules to move old messages, nothing happens.  I have tried both of the options under "Apply rules" ("selected messages" and "all messages"), and they seem to do nothing at all.  No messages get moved.

I have found a few old discussions here that touch on this, but can I confirm that this function is truly broken — or am I missing something?
