If I understand you correctly, I can chose one of the three options you
presented to me, right? If so,
	3) I did until now.
	2) no way.
To 1):
I now set
	mail_privileged_group = mail

	drwxrwx--x  94 root  mail  3072 Dec 18 01:43 /var/mail

But I still get the same error. The LMTP and the IMAP process do still
get executed under group %u, when they try to create the mailbox. What's
wrong?

Thank you for your help!
	
Best regards, Adrian.
