dovecot-lda - Dovecot's local mail delivery agent
SYNOPSIS
       dovecot-lda [-ek] [-a address] [-c config_file] [-d username] [-f enve-
       lope_sender] [-m mailbox] [-o setting=value] [-p path] [-r address]
DESCRIPTION
       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:
       o   Mailbox indexing during mail  delivery,  providing  faster  mailbox
           access later
       o   Quota enforcing by the quota plugin
       o   Sieve language support by the Pigeonhole sieve plugin
OPTIONS
       Options accepted by dovecot-lda:
       -a address
           Destination  address  (e.g.  user+ext@domain).  If  not  specified,
           default is based on the lda_original_recipient_header setting  set-
           ting.
       -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. If not specified and message data begins
           with a valid mbox-style "From " line, the address is taken from it.
       -k
           Don't clear all environment at startup.
       -m mailbox
           ). If the mailbox doesn't exist, it will  not  be  created  (unless
           lda_mailbox_autocreate  setting). If a message couldn't be saved to
           the
               o   If Sieve plugin is used, this mailbox is used as  the  keep
                   action's  mailbox.  It's  also  used  if  there is no Sieve
                   script or if the script fails for some reason.
               o   Deliveries to namespace prefix will result  in  saving  the
                   mail to INBOX instead. For example if you have Mail/ names-
                   pace, this allows you to specify dovecot-lda -m Mail/$mail-
                   box  where  mail  is stored to Mail/$mailbox or to INBOX if
                   $mailbox is empty.
               o
                    directory, your namespace configuration is  namespace_pre-
                   fix  setting  and  namespace_separator setting, the correct
                   way to deliver mail there is to use
       -o setting=value
           Overrides the configuration setting from  /etc/dovecot/dovecot.conf
           and from the userdb with the given value. In order to override mul-
           tiple 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 possi-
           ble. 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  neces-
           sary.
       -r address
           Final  envelope  recipient address. Defaults to -a address, but may
           differ if, e.g., aliases are used  or  when  dropping  the  +detail
           part.
EXIT STATUS
       dovecot-lda will exit with one of the following values:
       0
           Delivery was successful. (EX_OK)
       64
           Invalid parameter given. (EX_USAGE)
       67
           Recipient user not known. (EX_NOUSER)
       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)
