Putting subject & from in mail from command line

I couldn’t figure out how to send an email with both the subject and from set from the command line.

mail -s "my subject" example@foo.bar

worked with mail but would only set the subject.

sendmail -f "sender@foo.bar" receiver@foo.bar

worked with sendmail but would only set the “from”. With a little help from Google I put this together:

#!/bin/bash
HOST=`hostname | awk 'BEGIN { FS="." } ; {print $1}'`
DOMAIN=`hostname`
PASSWORD='mypassword'
BODY=`tail -n 40 /var/log/maillog`
FROM="$HOST@$DOMAIN"
TO='receiver@foo.bar'
SUBJECT="Last 40 lines of maillog"
(
echo "From: $FROM"
echo "Subject: $SUBJECT"
echo "To: $TO"
echo "$BODY"
) | sendmail -f $FROM $TO

I couldn’t find a script to search the Postfix mail queue so I wrote one. It’s a bash script and can be downloaded here (or just copy and paste it to file of your choice). I call it ssubject.sh. It ends up just spitting out the queue id’s of messages that match. Usage: “ssubject.sh “some words to look for”

#!/bin/bash
SUBJECT=$1
/usr/sbin/postqueue -p | awk {'print $1'} | grep -v (host | \\
grep -v @ | grep -v (delivery | grep -v (Host | grep -v (connect | \\
grep -v (lost | grep -v (conversation | grep -v -Queue | \\
sed 's/*//g' | sed '/^$/d' > /tmp/queue_ids.txt
cat /tmp/queue_ids.txt | while read line; do
sudo /usr/sbin/postcat -q ${line}|> | grep "$SUBJECT" > /dev/null 2>&1
if [ "$?" -eq "0" ]; then
echo ${line}|> ;
fi
done
