[Dovecot] When dovecot delivery, nested maildir (<user>/maildir/maildir) is "auto"created
Scenario: Sogo/Mysql+Postfix+Dovecot(only IMAP)+LDAP (Active Directory)
To make clean the understand of my issue I've performed those step go to /var/vmail/utente2 and perform in this directory "rm -rf *"
After I send email to utente2 via "telenet localhost 25"
I return to /var/vmail/utente2 and perform "ls -la" that shows me: maildir |-maildir |-cur |-new |-tmp
but the expected results was |-maildir |-cur |-new |-tmp
the relevant part of telnet session is: Mar 05 19:53:17 auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Mar 05 19:53:17 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libauthdb_ldap.so Mar 05 19:53:17 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so Mar 05 19:53:17 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libmech_gssapi.so Mar 05 19:53:17 auth: Debug: auth client connected (pid=3286) Mar 05 19:54:35 auth: Debug: master in: USER 1 utente2/maildir/@domain.local service=lda Mar 05 19:54:35 auth: Debug: master out: USER 1 utente2/maildir/@domain.local uid=500 gid=500 home=/var/vmail/utente2/maildir/@domain.local Mar 05 19:54:35 lda: Debug: auth input: utente2/maildir/@domain.local uid=500 gid=500 home=/var/vmail/utente2/maildir/@domain.local Mar 05 19:54:35 lda(utente2/maildir/@domain.local): Debug: Effective uid=500, gid=500, home=/var/vmail/utente2/maildir/@domain.local Mar 05 19:54:35 lda(utente2/maildir/@domain.local): Debug: Home dir not found: /var/vmail/utente2/maildir/@domain.local Mar 05 19:54:35 lda(utente2/maildir/@domain.local): Debug: maildir++: root=/var/vmail/utente2/maildir//maildir, index=, control=, inbox=/var/vmail/utente2/maildir//maildir Mar 05 19:54:35 lda(utente2/maildir/@domain.local): Debug: none: root=, index=, control=, inbox= Mar 05 19:54:35 lda(utente2/maildir/@domain.local): Info: msgid=20130305185423.6E56B407B6@posta.domain.local: saved mail to INBOX
NB: note the wrong path of inbox inbox=/var/vmail/utente2/maildir//maildir
From SOGO when I login the "autocreate" work well: in root folder of "utente2" I can see |-maildir |-cur |-new |-tmp
But if I send email from SOGO frontend, same error of "telnetting" *What is wrong in my config?*

When I interprete lines 1 and 2 correctly, you pass "utente2/maildir/@domain.local" as username to Dovecot. Line 3 evaluates your homedir using "%Lu" correctly, 6th line is using "%n" variable, which resembles to "utente2/maildir/"; there you get the double "maildir//maildir" - note the double /, too, one from the username, one from the mail_location pattern.
For some reason, I do not know, you allow "/" in usernames, hence, they gets passed to the path of homedir and mail location.
The only question now is, do you really send the message to: utente2/maildir/@domain.local
or does Postfix mangles the recipient in some way?
Via SoGo you do logon with utente2 instead of "utente2/maildir/@domain.local", hence, there is just one "maildir" autocreated, because "%n" is substituted by "utente2" instead of "utente2/maildir/".
From SOGO when I login the "autocreate" work well: in root folder of "utente2" I can see |-maildir |-cur |-new |-tmp
mail_location = maildir:/var/vmail/%n/maildir userdb { args = uid=500 gid=500 home=/var/vmail/%Lu allow_all_users=yes

Hmm, utente2 became utente2/maildir/@domain.local again. I have no experience with postfix, so I would first make sure, postfix passes the correct values to the Dovecot LDA, by:
create wrapper script: ===== START #!/bin/bash
( date echo arguments "$@" id /usr/libexec/dovecot/deliver "$@" rc=$? echo rc=$rc exit $rc ) >> /tmp/dovecot-lda-wrapper.$$.log 2>&1 ==== END
/etc/postfix/master.cf (relevant) # Dovecot LDA dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/path/to/wrapper -f ${sender} -d ${recipient}
see changed argv= argument.
Then check the created log files in /tmp, if the argument of "-d" does or does not contain the "/maildir/" part.
If it does, you will have to check your postfix installation, when the recipient string gets changed. Maybe your postfix was configured to deliver to Maildirs directly before and therefore at some point the "/maildir/" is added.

what do you think of this? what postfix config to check?

*SOLVED* modifyng /etc/postfix/ldap-users.cf (relevant)
from query_filter = (&(objectclass=person) (mail=%s)) result_attribute = sAMAccountName version = 3 result_format=%s/Maildir/
to query_filter = (&(objectclass=person) (mail=%s)) result_attribute = sAMAccountName version = 3 *result_format=%s*
ThankU for your support
