Well, I've been all day yesterday solving this .. and of course a simple [root@magenta ~]# chmod a+rx /opt/mailboxes/

allows me to see the mails from scanner user.

The only problem now is when sending mails to that user I still get a warning: connect #3 to subsystem private/dovecot: Connection refused

I don't think I can set postfix to deliver directly to maildir instead of passing through dovecot ? I don't know if the home_mailbox directive allows us to use vars like %u ? or can you see anything wrong in my confs !?

What version of Postfix?

Do you have the following in main.cf? Postfix must know where to find the Dovecot delivery agent. In your main.cf snippet you tell Postfix to deliver to Dovecot but you don't tell how. You need the how:

mailbox_command = /usr/local/libexec/dovecot/deliver # or mailbox_command = /usr/libexec/dovecot/deliver # or mailbox_command = /usr/lib/dovecot/deliver # or wherever it was installed in your system.

Get dovecot LDA working. There's no reason you can't. But, to answer your other question, yes, you can have Postfix drop mail directly into maildirs. Both questions are answered here. Hit the web page, as all the parameters are hot linked to more thorough usage information.

MAILBOX DELIVERY The default per-user mailbox is a file in the UNIX mail spool directory (/var/mail/user or /var/spool/mail/user); the location can be specified with the mail_spool_direc- tory configuration parameter. Specify a name ending in / for qmail-compatible maildir delivery.

   Alternatively, the per-user mailbox can be a file  in  the
   user's  home  directory  with  a  name  specified  via the
   home_mailbox configuration parameter. Specify  a  relative
   path name. Specify a name ending in / for qmail-compatible
   maildir delivery.

   Mailbox delivery can be delegated to an  external  command
   specified  with  the mailbox_command_maps and mailbox_com-
   mand configuration parameters. The command  executes  with
   the  privileges  of  the  recipient user (exceptions: sec-
   ondary groups are not enabled;  in  case  of  delivery  as
   root,   the   command  executes  with  the  privileges  of
   default_privs).

   Mailbox delivery can be delegated to  alternative  message
   transports  specified  in  the  master.cf file.  The mail-
   box_transport_maps  and  mailbox_transport   configuration
   parameters  specify  an optional message transport that is
   to be used for all local recipients, regardless of whether
   they  are  found  in  the UNIX passwd database.  The fall-
   back_transport_maps  and   fallback_transport   parameters
   specify  an optional message transport for recipients that
   are not found in the aliases(5) or UNIX passwd database.

   In the case of UNIX-style mailbox delivery,  the  local(8)
   daemon prepends a "From sender time_stamp" envelope header
   to each message, prepends an  X-Original-To:  header  with
   the  recipient  address  as  given to Postfix, prepends an
   optional Delivered-To:  header  with  the  final  envelope
   recipient address, prepends a Return-Path: header with the
   envelope sender address, prepends a > character  to  lines
   beginning  with  "From  ", and appends an empty line.  The
   mailbox is locked for exclusive access while  delivery  is
   in  progress.  In  case of problems, an attempt is made to
   truncate the mailbox to its original length.

   In the case of maildir delivery, the local daemon prepends
   an  optional  Delivered-To: header with the final envelope
   recipient address, prepends an X-Original-To: header  with
   the  recipient address as given to Postfix, and prepends a
   Return-Path: header with the envelope sender address.

Hi,

to diagnose, can you provide full output of 'dovecot -n' plus the dovecot LDA excerpexcerptom Postfix's 'master.cf'?

Regards Thomas

... ouch... Of course this should read: excerpt from 'master.cf' :)
