Here's what we got working. The aim was to attach a file (defined here as $account_file).



echo "From: ${from_email_address}" > $MSG_FILE
echo "To: ${to_email_address}" >> $MSG_FILE
echo "Subject: ${Subject_Text}" >> $MSG_FILE
echo "Mime-Version: 1.0" >> $MSG_FILE
echo 'Content-Type: multipart/mixed; boundary="GvXjxJ+pjyke8COw"' >> $MSG_FILE
echo "Content-Disposition: inline" >> $MSG_FILE
echo "" >> $MSG_FILE
echo "--GvXjxJ+pjyke8COw" >> $MSG_FILE
echo "Content-Type: text/plain" >> $MSG_FILE
echo "Content-Disposition: inline" >> $MSG_FILE
echo "" >> $MSG_FILE
echo "blah blah... (email content)" >> $MSG_FILE
echo "" >> $MSG_FILE
echo "" >> $MSG_FILE
echo "--GvXjxJ+pjyke8COw" >> $MSG_FILE
echo "Content-Type: text/plain" >> $MSG_FILE
echo "Content-Disposition: attachement; filename=${account_file}" >> $MSG_FILE
echo "" >> $MSG_FILE
echo "" >> $MSG_FILE
cat $account_file >> $MSG_FILE

cat $MSG_FILE | /usr/lib/sendmail -t
