I've been playing with encrypting mail from/to postfix and did create some
errors. postfix tried to send me an error mail, but failed:

6C7944E1B2      784 Thu Dec 26 06:26:10  root at jochen.org
 (connect to kolab3.jochen.org[/var/lib/imap/socket/lmtp]: Permission denied)
                                         jochen at jochen.org

The permissions are as follows:

root at kolab3:/etc/roundcubemail# ls -l /var/lib/imap/socket/lmtp
srwxrwxrwx 1 root root 0 Dez 29 08:26 /var/lib/imap/socket/lmtp
root at kolab3:/etc/roundcubemail# ls -ld /var/
drwxr-xr-x 12 root root 4096 Nov 17 06:08 /var/
root at kolab3:/etc/roundcubemail# ls -ld /var/lib/
drwxr-xr-x 40 root root 4096 Dez 17 20:11 /var/lib/
root at kolab3:/etc/roundcubemail# ls -ld /var/lib/imap/
drwxr-x--- 13 cyrus mail 4096 Dez 29 21:56 /var/lib/imap/
root at kolab3:/etc/roundcubemail# ls -ld /var/lib/imap/socket
drwxr-x--- 2 cyrus mail 4096 Dez 29 08:26 /var/lib/imap/socket

Since the user postfix is not member of the group mail the socket is
I see two choices, either allow access for all to the directories 
(I don't like that) like that:

> chmod o+rx /var/lib/imap
> chmod o+rx /var/lib/imap/socket

I finally added the user postfix to the mail group and the mails
were delivered after a postfix restart.

Shouldn't the postix user be member of group mail when the packages is
