.SH OPTIONS
Options accepted by
.BR dovecot\-lda :
.\"-------------------------------------
.TP
.BI \-a\  address
Destination address (e.g. user+ext@domain). Default is the same as
.IR username .
.\"-------------------------------------
.TP
.BI \-c\  config_file
Alternative configuration file path.
.\"-------------------------------------
.TP
.BI \-d\  username
Destination
.IR username .
If given, the user information is looked up from userdb.
Typically used with virtual users, but not necessarily with system users.
.\"-------------------------------------
.TP
.B \-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.
.\"-------------------------------------
.TP
.BI \-f\  envelope_sender
Envelope sender address.
.\"-------------------------------------
.TP
.B \-k
Don\(aqt clear all environment at startup.
.\"-------------------------------------
.TP
.BI \-m\  mailbox
Destination mailbox (default is
.BR INBOX ).
If the mailbox doesn\(aqt exist, it will not be created (unless the
.I lda_mailbox_autocreate
setting is set to
.BR yes ).
If a message couldn\(aqt be saved to the
.I mailbox
for any reason, it\(aqs delivered to
.B INBOX
instead.
.\"---------------------------------
.TP
.BI \-o\  setting = value
Overrides the configuration
.I setting
from
.I /etc/dovecot/dovecot.conf
and from the userdb with the given
.IR value .
In order to override multiple settings, the
.B \-o
option may be specified multiple times.
.\"-------------------------------------
.TP
.BI \-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\(aqt be used unless really necessary.
.\"------------------------------------------------------------------------

will exit with one of the following values:

.TP
.B 77

option was used and mail was rejected.
Typically this happens when user is over quota and

is configured. (EX_NOPERM)

file for details. (EX_TEMPFAIL)
