-A "header: value"
Add a header to the autoresponse. Multiple -A
options are allowed. In most situations, the -A option must be used to
set the “From:” header in the autogenerated response.
-faddress
Address the autoresponse to address, which must be
an RFC 2822[1] address. By default mailbot takes the
autoresponse address from the From: (or the Reply-To:) header in the original
message. -f, if present, overrides and explicitly sets the autoresponse
address. "address" must immediately follow the -f
option without an intervening space (it's a single command line argument). An
-f option without an address takes the address from the
SENDER environment variable.
-t filename
Read text autoresponse from
filename, which must
contain a plain text message in “flowed-text” format. In a
“flowed-text”-formatted message, each line that ends with a
space character indicates that the line logically flows into the next line.
This allows the message to be reformatted for any shown display width.
Note
Messages in languages (see the
-c option) which use spaces as word
delimiters must have
two spaces at the end of a flowed line. The last
space on a flowed line is logically removed, and the first space separates the
last word on the previous line from the first word on the next line.
Otherwise, the two words will not have a logical space between them if they
get repositioned as part of adjusting the message's width for display.
Messages in ideographic languages that do not use spaces as word
delimiters need only one space trailing a flowed line.
Note
The trailing whitespace has no visual impact when shown by software that does
not implemented flowed text format, and always displays messages using their
original width.
-c charset
Set the autoresponse's MIME character set to
charset. Run mailbot without any arguments to see the default
character set.
-m filename
Read a MIME autoresponse from filename. This is similar
to the
-t option, except that
filename contains MIME headers,
followed by a blank line, and the corresponding MIME content. The contents of
filename are inserted in the autoresponse without further processing.
The specified file must contain the “Content-Type”
header specifying the “text/plain” MIME type, with the
“format=flowed”, “delsp=yes”, and the
“charset” attributes, which override the -c parameter.
If the specified file has a “Content-Transfer-Encoding” header
it must be either “7bit” or “8bit”, it may not
be “quoted-printable”. mailbot always drops any
existing “Content-Transfer-Encoding” header and always adds
the “Content-Transfer-Encoding: 8bit” header, even with the
-m, since the salutation inserted into the message includes the
sender's name, which may contain 8-bit characters. Example:
Content-Type: text/plain; format=flowed; delsp=yes; charset="iso-8859-1"
Mary had a little lamb,
Its fleece was white as snow.
And everywhere Mary went,
The lamb was sure to go.
Note
When the
-m option is specified
mailbot ignores the locale's
character set and formats the autoreply according to the character set read
from the “Content-Type” header.
-M address
Format the autoresponse as a delivery status notification
(RFC 1894[2]). address is an RFC 2822[1] E-mail address
that generates the DSN. Note that the -A option should still be used in
addition to -M in order to set the From: header on the autoresponse.
-M sets the DSN address only. The -M option automatically sets
-T replydsn
-R type
Specify the feedback report type, with type set to
abuse, fraud, other, or virus. Must be used together with “-T
feedback” or “-T replyfeedback”.
-T format
Set the reply format.
format must be one of the
following values:
•“reply” - the default reply
format.
•“replyall” - like
“reply”, except also puts the recipients in the original
message's “To:” and “Cc:” headers into the
“Cc:” header of the generated reply.
•“replydsn” - like
“reply”, except the message is formatted as a delivery status
notification.
•“replydraft” - like
“reply”, with the text of the autoresponse coming from a maildir
specified by the -l option. See “Autoreplies from a maildir
folder”, below.
•“forward” - attach the original
message as forwarded text.
•“forwardatt” - attach the original
message as a forwarded message attachment.
•“feedback” - generate an Email
Feedback Report message (see RFC 5965[3]). The “-R”
option is required when this is specified.
•“replyfeedback” - like
“feedback”, but also adds a “To:” header,
addressed to the original message's sender.
-N
Do not quote the contents of the original message in the
message created by “reply”, “replyall”,
“replydsn”, “feedback”, and
“replyfeedback” options.
Note
The original message gets quoted, in the absence of this option, only if the
original message was formatted as plain text.
mailbot is unable to
quote an original message which was formatted as HTML, or any other
non-plaintext format.
Note
For “replydsn”, “feedback”, and
“replyfeedback” options, the convention is to attach the
original message, or only its headers, separately; so this option should
always be specified for these three reply formats.
-a
Attach the entire message, for “replydsn”,
“feedback”, and “replyfeedback”, instead of only
its headers.
-e
Generate a reply (“reply”-formats) to the
address listed in any “Errors-To” or “Return-Path”
header, if present, instead of the “From” header.
-S “salutation”
Use the given
salutation in the
“reply”. The default value is “%F writes:”. The
following substitutions are recognized in the salutation string:
•%% - an explicit % character.
•%n - a newline character.
•%C - the “X-Newsgroup:” header from
the original message.
•%N - the “Newsgroups:” header from
the original message.
•%i - the “Message-ID:” header from
the original message.
•%f - the original message's sender's
address.
•%F - the original message's sender's name.
•%S - the “Subject:” header from the
original message
•%d - the original message's date, in the local
timezone.
•%{...}d - use strftime() to format
the original message's date. A plain %d is equivalent to %{%a, %d %b %Y
%H:%M:%S %z}d.
All other characters in the salutation string are left as is.
-F “marker”
When generating a forward, use the marker to
separate the forwarded message from the autoreply text, instead of the default
“--- Forwarded message ---”
-r addrlist
addrlist is a comma-separated list of RFC
2822[1] E-mail addresses. mailbot sends an autoresponse only if the
original message has at least one of the specified addresses in any To: or Cc:
header.
-d filename
Create a small database, filename, that keeps
track of senders' E-mail addresses, and prevent duplicate autoresponses going
to the same address (suppress autoresponses going back to the same senders,
for subsequent received messages). The -d option is only available if
maildrop has GDBM/DB extensions enabled.
-D x
Do not send duplicate autoresponses (see the -d
option) for at least x days (default: 1 day). The -d option
creates a database of E-mail addresses and the times an autoresponse was last
mailed to them. Another autoresponse to the same address will not be mailed
until at least the amount of time specified by the -D option has
elapsed.
-s "subject"
Set the Subject: header on the autoresponse to
subject.
-n
Show the resulting message, do not send it. Used for
debugging purposes.
--feedback-original-envelope-id "<envelopeid>",
--feedback-original-mail-from "<mailfrom>",
--feedback-reporting-mta "dns; hostname",
--feedback-source-ip aaa.bbb.ccc.ddd,
--feedback-incidents n,
--feedback-authentication-results "results",
--feedback-original-rcpt-to "<rcptto>",
--feedback-reported-domain example.com
Optional parameters to include in the feedback report
generated by “feedback” and “replyfeedback”.
mailbot always adds “Arrival-Date” with the current time,
as well as “Version” and “User-Agent”.
“--feedback-authentication-results”,
“--feedback-original-rcpt-to” and
“--feedback-reported-domain” may be specified more than
once.
-l maildir
Specifies the maildir for the “-T
replydraft” option. See “Autoreplies from a maildir
folder”, below.
In .mailfilter:
cc "| mailbot -T replydraft -l './Maildir/.Vacation' \
-d autoresponsedb \
-A 'From: info@domain.com' /usr/bin/sendmail -f ''"
to "./Maildir"
The -T replydraft reply format takes the content of the
autoresponse from the most recent message in a maildir. The -l option
specifies the maildir. The above example takes the message from
$HOME/Maildir/.Drafts which should be a maildir (with the usual cur, new,
and tmp subdirectories). It would typically get created by Courier-IMAP as a
folder named “Vacation”.
This makes it possible to install autoreplies via an IMAP client
by creating a folder named “Vacation”, and copying a message
into it. The contents of the message become the autoresponse.
If the named maildir does not exist, or is empty, mailbot
does nothing. If the named maildir has more than one message, the most
recent message gets used.
The above example uses additional mailbot options to
suppress duplicate autoresponses, and to set the “From:”
header on the autoresponse.
