Sendmail Png Attachments
I use sendmail to send html emails, my script works perfect and sends email with plain text attachment.

Now i need to attache png file to the email and this attachment part is not working.

Code:
(
echo "From: $FROM"
echo "To: $TO"
echo "MIME-Version: 1.0"
echo "Subject: $SUBJECT"
echo 'Content-Type: multipart/mixed; boundary="GvXjxJ+pjyke8COw"'
#echo "Content-Disposition: inline"
echo ""
echo "--GvXjxJ+pjyke8COw"
echo "Content-Type: text/html"
echo "Content-Disposition: inline"
cat TheMailer.html
echo ""
echo "--GvXjxJ+pjyke8COw"
echo "Content-Type: text/plain"
echo "Content-Disposition: attachement; filename=attachment_file.csv"
echo ""
cat attachment_file.csv
echo ""
echo "--GvXjxJ+pjyke8COw"
echo "Content-Type: image/png"
echo "Content-Disposition: attachment; filename=\"graph_file.png\""
echo "Content-Transfer-Encoding: base64"
) | /usr/sbin/sendmail -t


TheMailer.html contains all my html command and its works good .
I get my email with plain text attachment but i don't get the png attachment right , its just the file name with 0Kb

Appreciate your expert help in fixing this part

Code:
echo ""
echo "--GvXjxJ+pjyke8COw"
echo "Content-Type: image/png"
echo "Content-Disposition: attachment; filename=\"graph_file.png\""
echo "Content-Transfer-Encoding: base64"


Thank you

You didn't actually include the contents of the .png in there.

First try:
Code:
(
echo "From: $FROM"
echo "To: $TO"
echo "MIME-Version: 1.0"
echo "Subject: $SUBJECT"
echo 'Content-Type: multipart/mixed; boundary="GvXjxJ+pjyke8COw"'
#echo "Content-Disposition: inline"
echo ""
echo "--GvXjxJ+pjyke8COw"
echo "Content-Type: text/html"
echo "Content-Disposition: inline"
cat TheMailer.html
echo ""
echo "--GvXjxJ+pjyke8COw"
echo "Content-Type: text/plain"
echo "Content-Disposition: attachement; filename=attachment_file.csv"
echo ""
cat attachment_file.csv
echo ""
echo "--GvXjxJ+pjyke8COw"
echo "Content-Type: image/png"
echo "Content-Disposition: attachment; filename=\"graph_file.png\""
echo "Content-Transfer-Encoding: base64"
echo ""
openssl base64 < graph_file.png
) | /usr/sbin/sendmail -t

You specified just the MIME header, but the file is not attached!

Here is an example using uuencode for encoding:
Code:
echo "Content-Type: image/png"
echo "Content-Disposition: attachment; filename=\"graph_file.png\""
echo "Content-Transfer-Encoding: uuencode"
uuencode graph_file.png graph_file.png

Thanks Corona688 it worked

Code:
echo "--GvXjxJ+pjyke8COw"
echo "Content-Type: image/png"
echo "Content-Disposition: attachment; filename=\"graph_file.png\""
echo "Content-Transfer-Encoding: base64"
echo ""
openssl base64 < graph_file.png


I can live with the attachment but is it possible that we can include the contents in the mail body
