It's not.

The server does as its told. The behavior is related to the email 
clients used.

I'm not sure what is best, but I can explain what the problem is.

That is correct. IMAP was not really designed to be used with a trash 
mailbox. Instead you were intended to mark emails for deletion (using 
the `\Deleted` IMAP keyword) and then explicitly expunge them. Often 
email clients also offered to do this automatically when closing a 
mailbox.

When moving an email (e.g., to the trash) then what really happens is:

* The message is copied to the destination mailbox.
* The message is marked for deletion in the source mailbox (red dot 
state in MailMate).
* The message is expunged.

Some email clients mark for deletion and hide the messages from the user 
and then do the expunge later on. Your problem depends on how your other 
email clients define “later on”.

In MailMate there is no “later on”. Expunging is done immediately 
after deleting.

MailMate also supports the old style though since one can create a tag 
for the `\Deleted` keyword and use that to delete messages. Expunging 
can then be done using the 
[`expungeDeletedMessages:`](http://manual.mailmate-app.com/key_binding_selectors#mailbox_actions) 
key binding selector. This also requires the following hidden setting to 
always show deleted messages:

	defaults write com.freron.MailMate MmShowDeletedMessages -bool YES

Which leads me to your last comment:

> I'm not seeing any way to hide them in MailMate though.

You need to always hide them and this is not currently possible. By 
default, they are hidden for any mailboxes based on “All Messages” 
and the universal mailboxes, but they are not hidden for anything based 
on IMAP mailboxes. You could add a condition to each IMAP mailbox to 
hide these messages, but that would be a hassle.

I'm still considering how to improve/change this, but at least you know 
how it works now :-)

Oh, and you might have noticed that MailMate some times draws the entire 
line in the messages outline in red. This happens when deleting a 
message permanently -- it'll be red until it has been deleted on the 
server (and then it'll disappear completely). You would most often see 
this in the trash mailbox of an IMAP account.
