Okay, I solved this problem as follows:
Created a special user to do the vacation messages.
Added this to the .forward file of that special user
seen noerror pipe "/usr/local/bin/resend-vacation-email.sh"
Touch my-vacation-db file in the special user's home dir
Touch an empty .vacation file in the user whom is on vacation.
Here is the EDITED file used with the pipe:
# cat /usr/local/bin/resend-vacation-email.sh
#!/bin/bash
MESSAGE_ID=${2-no_message_id}
if [[ "${MESSAGE_ID}" = "no_message_id" ]]
then
TMPFILE=$(mktemp)
else
TMPFILE=/tmp/"${MESSAGE_ID}"
fi
BN_USER_HOME=$(basename "${HOME}")
TMPFILE="${TMPFILE}~${DOMAIN}~${BN_USER_HOME}"
env > "${TMPFILE}.env"
RESENT_BCC=
RESENT_TO=
REPLY_TO=no_reply_addr...@example.com
RESENT_FROM="${REPLY_TO}"
egrep -v 'dummy|^$' - > "${TMPFILE}.email-wrk"
RECEIVED=$(grep '^Received:' < "${TMPFILE}.email-wrk"|awk '{print $3}')
SUBJECT=$(grep '^Subject:' < "${TMPFILE}.email-wrk"|awk -F~ '{print $1}')
RESENT_TO=$(grep '^Subject:' < "${TMPFILE}.email-wrk"|awk -F~ '{print $2}')
TESTX=$(grep '^Subject:' < "${TMPFILE}.email-wrk"|awk -F~ '{print $3}')
[[ ${TESTX} = " special-random-string" ]] || exit 1
SDATEX_NOW=$(date +%s)
SDATEX_OLD=$(date +%s -d "-14 days")
[[ -f my-vacation-db ]] && {
RECORDX=''
RECORDX=$(
grep "${RECEIVED}~${RESENT_TO:1}~1" < my-vacation-db | \
awk -F~ '{print $3}'
)
if [[ ".${RECORDX}" = "." ]]
then
# add record for my own vacation database
echo "${RECEIVED}~${RESENT_TO:1}~${SDATEX_NOW}" >>
my-vacation-db
else
# exit if already sent vacation message in last 14 days
[[ ${RECORDX} -gt ${SDATEX_OLD} ]] && exit 1
sed -i "/${RECEIVED}~${RESENT_TO:1}~1/d" my-vacation-db
echo "${RECEIVED}~${RESENT_TO:1}~${SDATEX_NOW}" >>
my-vacation-db
fi
}
(
echo "Reply-To: ${REPLY_TO}"
[[ -z "${RESENT_BCC}" ]] || echo "Resent-Bcc: ${RESENT_BCC}"
echo "Resent-From: ${RESENT_FROM}"
[[ -z "${RESENT_TO}" ]] || echo "Resent-To: ${RESENT_TO}"
echo "Resent-Date: $(/bin/date -R)"
echo "To: ${RESENT_TO:1}"
echo "${SUBJECT}"
[[ -f .vacation_special ]] && cat .vacation_special
) | tee "${TMPFILE}.new" | /usr/sbin/sendmail -ti
exit 0
And here is my exim4 config file:
# cat /etc/exim4/conf.d/transport/15_user_vacation
uservacation_transport:
driver = autoreply
file = $home/.vacation
file_expand
once = $home/.vacation.db
# to use a flat file instead of a db specify once_file_size
#once_file_size = 2K
once_repeat = 14d
#from = $local_part@$domain
from = no_reply_address@$domain
#to = $sender_address
#subject = "Re: $h_subject"
bcc = special_vacat...@example.com
subject = "Re: $h_subject ~ $sender_address ~ special-random-string"
And this is the content of the html file for the emails:
# cat .vacation_special
Content-Type: multipart/alternative; boundary="--foo"
----foo
Content-Type: text/plain; charset="UTF-8"
Content-Transfer-Encoding: quoted-printable
Merry Christmas & Happy New Year!
We close on 5pm Friday, December 20 and our office re-opens Wednesday,
January 8, 2020
----foo
Content-Type: text/html; charset="UTF-8"
Content-Transfer-Encoding: quoted-printable
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN"
"http://www.w3.org/TR/REC-html40/strict.dtd";>

<HEAD>
<TITLE>Christmas Message</TITLE>
<BODY>
<img src="https://example.com/Christmas%20Banner%201920x576.png";
alt="Christmas Message">
</BODY>
</HTML>
----foo--
Now, if the special user receives email that doesn't have the special
string in the subject line, then it is dropped. If it does have the
special string, then it continues and works out (and keeps track of) if
the vacation message has been sent in the last 14 days or not (resend
once per 14 days per sender).
The special file for vacation is common for the business (Christmas
clousre). A little tweaking and I can have personalized html files per
user in the one area of the special_vacation_use, such as:
user1.vacation_special
user2.vacation_special
- and then use the "${RECEIVED}" variable from the script with the file
name....
Kind Regards
