       dovecot-lda - Dovecot's local mail delivery agent


       dovecot-lda  [-ek]  [-a  address]  [-c config_file] [-d username] [-f envelope_sender] [-m
       mailbox] [-o setting=value] [-p path]


       The dovecot-lda is a local mail delivery agent which takes mail from an MTA  and  delivers
       it to a user's mailbox, while keeping Dovecot index files up to date.

       Main features of the dovecot-lda are:

       *   Mailbox indexing during mail delivery, providing faster mailbox access later

       *   Quota enforcing by the quota plugin

       *   Sieve language support by the Pigeonhole sieve plugin


       Options accepted by dovecot-lda:

       -a address
              Destination address (e.g. user+ext@domain). Default is the same as username.

       -c config_file
              Alternative configuration file path.

       -d username
              Destination  username.   If  given,  the user information is looked up from userdb.
              Typically used with virtual users, but not necessarily with system users.

       -e     If mail gets rejected, write the rejection reason to stderr and exit with status 77
              (EX_NOPERM).  The default is to send a rejection mail ourself.

       -f envelope_sender
              Envelope sender address.

       -k     Don't clear all environment at startup.

       -m mailbox
              Destination  mailbox (default is INBOX).  If the mailbox doesn't exist, it will not
              be created (unless the lda_mailbox_autocreate setting is set to yes).  If a message
              couldn't be saved to the mailbox for any reason, it's delivered to INBOX instead.

       -o setting=value
              Overrides  the  configuration  setting  from /etc/dovecot/dovecot.conf and from the
              userdb with the given value.  In order to override multiple settings, the -o option
              may be specified multiple times.

       -p path
              Path  to  the mail to be delivered instead of reading from stdin.  If using maildir
              the file is hard linked to the destination if possible.  This allows a single  mail
              to  be delivered to multiple users using hard links, but currently it also prevents
              deliver from updating cache file so it shouldn't be used unless really necessary.


       dovecot-lda will exit with one of the following values:

       0   Delivery was successful. (EX_OK)

       64  Invalid parameter given. (EX_USAGE)

       77  -e option was used and mail was rejected.  Typically this happens when  user  is  over
           quota and quota_full_tempfail = no is configured. (EX_NOPERM)

       75  A  temporary  failure.  This is returned for almost all failures. See the log file for
           details. (EX_TEMPFAIL)
