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)
