Hi,
if my red ip address change, I would like to send an e-mail.
I can run the test e-mail
System | Mail Service [Send testmail]
but
cat email_test | sendmail vorname.nachname@gmx.at -f
does not work.
Sorry I cannot post more Details as I’m new here I’m only allowed to post 2 links … ?
Any Ideas?

Hallo @alexander

Welcome to the IPFire community.

Here is a link to a\one of the config files used by the apcupsd addon to send an email using the dma system.

You should be able to use it to figure out how to structure your script.

Keep in mind that gmx does not accept mails from known dial-up ip addresses.

Hello Adolf,
thx a lot for this link.
I was able to solve my problem.
I removed in /var/ipfire/dma/dma.conf
MASQUERADE vorname.nachname@gmx.at
with this entry System | Mail Service [Send test mail] did not work anymore.

this is my bash script:

#/bin/bash
IP=$(/sbin/ip address | /bin/grep inet | /bin/grep red0 | /usr/bin/cut -b 10-22)
IP_alt=$(/bin/cat /root/mail/ip_red_alt)
/bin/echo $IP
/bin/echo $IP_alt
if [[ "$IP" != "$IP_alt" ]]; then
    echo "IP address change!";
    echo $IP > /root/mail/ip_red_alt
SUBJECT="IP Adresse: "$IP
FROM="alexander.kratky@gmx.at"
TO="alexander.kratky@gmx.at"
(
echo From: $FROM
echo To: $TO
echo Subject: $SUBJECT
) | sudo -u nobody /usr/sbin/sendmail -t -f $FROM
else
   echo "IP address did not change!";
fi
exit 0

in the subject of the mail I find my IP Address.
I was not able to send also a mail body.
But I’ve my information …

Hi Arne,
thx for your input. my script works now! I think this policy is valid if I run a mail server. As I understand it, I use something like a mail client.
