DOVECOT-LDA(1) Dovecot DOVECOT-LDA(1)

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 /usr/local/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)

/usr/local/etc/dovecot/dovecot.conf
Dovecot's main configuration file.
/usr/local/etc/dovecot/conf.d/10-mail.conf
Mailbox locations and namespaces.
/usr/local/etc/dovecot/conf.d/15-lda.conf
LDA specific settings.
/usr/local/etc/dovecot/conf.d/90-plugin.conf
Plugin specific settings.
/usr/local/etc/dovecot/conf.d/90-quota.conf
Quota configuration.
