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)
