Postfix/dovecot: user unrecognized, file permissions being misread

Hello all. Have spent several days following the excellent tutorial:

http://www.binarytides.com/install-postfix-dovecot-debian/

but still fail to have the user recognized and am getting log entries
that the mail directories are 0755 when I can clearly see that they are
0774.

Very puzzling, any help would be deeply appreciated.

Best regards, Andy
=========== Details ==========? I can add directories under IMAP, so my IMAP
login and permissions
must be correct.

? I can create an outgoing message under IMAP, but clicking SEND just
hangs. Logs do not indicate problem.

? I clearly can send it a message with smtp. The message is delivered
to postfix, but then dovecot fails to deliver it to a mailbox.
	------------------------------------ Log Entries ---------------------

/var/mail/vhosts/privustech.com/alavarre, dir owned by 0:0 mode=0755) 
However, the mail directory /var/mail/vhosts/privustech.com/alavarre is
	 -rwxrwxr-- vmail:vmail and I have restarted both postfix and dovecot.

========================System is openSUSE Leap 42.1 (64). postfix and dovecot
with SASL authentication, connecting through a Unix socket:
	/etc/postfix/main.cf:
		virtual_transport = lmtp:unix:private/lmtp
		
	/etc/dovecot/conf.d/10-master.cf:			service lmtp {
		  unix_listener /var/spool/postfix/private/lmtp {
			mode = 0600
				user = postfix
				group = postfix

		  }
The lmtp socket is owned by postfix, while the mail system is owned by vmail,
per the tutorial.

------------------------------

I am using virtual users (not system users) defined in
/etc/dovecot/dovecot-users:
	alavarre at privustech.com:{plain}ksaj;flkasjd;ds;f
	
Thanks in advance, Andy

I'm guessing vmail can't +w somewhere along the path of
/var/mail/vhosts/etc...

Edgar hello. Thanks again.
Not sure of the protocol. Perhaps better to keep the entire thread
complete, so here again is doveconf -n with the precendents:
