could be. However, following your mail I tried several alternatives for 
grouping, made the user itself part of mail group, made postfix and 
dovecot part of the users real group, made all part of roots real group, 
made the users part of postfix and dovecot real group ... I could have 
made failures in trying all this combinations but the failure remained 
in any case. (I switched all back for security reasons, the failure is 
still there.)

these are my lines from /etc/postfix/main.cf:
#mailbox_command = procmail -a "$EXTENSION"
mailbox_command = /usr/lib/dovecot/deliver

if I switch procmail back on the input gets delivered and I can see 
them using roundcube as a client for dovecot.

LMTP would be new to me and I fear just other hard-to-understand 
configuration topics.
What I did as a workaround is to have a last rule in each 
.dovecot.sieve: fileinto "rest". It works and this way the INBOX is no 
longer needed.

Do not understand how they have solved the problem. Changing 0660 to 
0600 for the /var/mail/user mboxes (with user:mail for user:group) seems 
not to be a logical solution - have not tried that.
