Unable to open message (POP3 retr)

[qmail-return-28276-archive=jab . org]

Hi all

When a mail is succesfully delivered, and I want to read it from pop3 the
following happens:
>   telnet mail.domain.com 110
    Trying w.x.y.z
    Connected to domain.com.
    Escape is...
    +OK ...
>   user johndoe
    +OK
>   pass pop3password
    +OK
>   list
    1 265
    .
>   retr 1
    -ERR unable to open that message
>   quit

the messages in domain-com/johndoe/Maildir/new/ is created with these permissions
    -rw------- 1 popuser popuser 265 jul 27 12:00 xxxxxx.domain.com

popuser is a user with shell=/bin/false

It seems that mails are created with wrong permission? OR??
If I manually change permission to -rw-rw---- I can "retr" the mail though.

Anyone knows how to setup the correct permissions?
And what ARE the default permission-settings on a newly arrived mail?
