Default mailbox setup?

[Internet54]

What is the default mailbox setup for a new domain and new email account?

I transferred from cPanel many moons ago and I have NEVER had any webmail program working the way it is supposed to. Yes, they show the mail that is in the inbox just fine, but it does not store any mail that is sent, trashed, saved, etc.

For example, when I login to squirrel mail I see the
Inbox
Sent
Trash
Spam
.INDEX.Sent
.INDEX.Trash
.INDEX.Spam

Advice appreciated.

More information needed. Squirrelmail works fine for me.
