[Dovecot] mkdir no permission

[Anna Obertacke]

Hallo list-member,

Please ignore my bad english. I cant wright bad but i understand well.
I reinstalled my server and have big problems with (V 1.1.11) dovecot  
now.
I work with Ubuntu 9.04 Server and want to use pop and imap with easy
configuration. I fetch all my Mails on the server and want to look  
them up
by apple Mail.

Until yesterday dovecot only worked after I logged in and did  
something on
the server, for example call "mail" oder call "mail.log".
After reinstall yesterday it works no more. The new entry in log is
"Internal error".
Anything else was before yesterday also.

My Error Logs:

mail.log:
May 19 10:00:38 ubuntu dovecot: POP3(annalein):
mkdir(/home/annalein/Maildir/cur) failed: Permission denied

annalein)

My configuration ist in dovecot-postfix.conf. I can't call it by dovecot
-n. But i changed allmost nothing from default-
disable_plaintext_auth=no
Some points in the file:
protocols = imap pop3 imaps pop3s managesieve
mail_location = maildir:~/Maildir


Please tell what i should show you.
Thank you for help.

Greetings, Anna Obertacke.
