That means: Dovecot sees them, but your client is not.
Are you absolutely sure the client is set to "display all folders"?
Secondly, make sure Thunderbird rescans the folders. Sometimes you need to 
collapse *certain* levels and expand them. I mean, collaps the whole tree 
of the account, then expand it again, see if the triangle in front of 
Dennis Email appeared, tap there, a.s.o. I have a Thunderbird client, that 
for whatever reason I don't know, "forgets" about a certain hierarchie 
(subtree) now and then.

As another test, you could speak IMAP:

telnet localhost 143
1 login mpress "pwd"
2 list * *
3 lsub * *

You could manually add those to the subscription file, if LSUB does not 
display the folders. LSUB displays only subscribed folders, LIST displays 
all.
