Are Docker install event alerts via SSMTP possible or is Event Server required?

[deebee]

Love ZM!.... and now with Docker!! - appreciative of the genius and effort put into creating this fantastic application!

My question for the good people of the forum:
I had ZM running for several years (straight install/Lubunu) with email notifications; all worked fantastic.
Upgraded to Lubuntu 20 recently and now trying ZM on Docker and love it.. but cannot get email notifications to work via ssmtp.
Read a bunch but couldn't find a straight answer so hoping someone can help answer a likely silly question directly:
For email notifications to work on Docker 'install', can I use ssmtp or does Docker require Event Server?

Context:
My manual tests from CLI (eg echo "Hello, World" | mail -s "My email check" user@gmail.com) work fine so ssmtp config is good.
Followed instructions to set up ssmtp (https://wiki.zoneminder.com/How_to_get_ ... Zoneminder).
But when I try to send email alert via ZM (eg filter/email details of all matches).. I get error in ZM log: "Unable to send email: error closing /usr/lib/sendmail: (exit 256)"... and no email alert .

tail -f /var/log/syslog shows my successful manual CLI commands but nothing shows up regarding failed attempts via ZM.

Thanks so much for any insights!!

MSMTP is recommended after Stretch. SSMTP is abandoned and doesn't work with certain type of email auth types.

Event server is not required for emails in normal ZM. I can't speak for docker, but I doubt its required.

Email disambiguation is here: https://wiki.zoneminder.com/Email. If you read through those docs, they should cover everything. Although I haven't heard of people using email alerts in Docker, there's no reason it shouldn't work. Buster needs to disable apparmor for msmtp.

Please refer the following link to get the details on installing MSMTP
https://bkjaya.wordpress.com/2019/10/21 ... ntu-19-04/
If the MSMTP is not installed in the docker zoneminder image that you are using , you will have to install it within the container as follows
Suppose the name of the container is "zm"
On the terminal run
sudo docker start zm
sudo docker exec -t -i zm /bin/bash ( to open the container )
apt update
apt install msmtp
ln -s /usr/bin/msmtp /usr/sbin/sendmail
exit
Prepare a file msmtprc in the home folder of the host (refer the link to get the codes for msmtprc )
Then copy a msmtprc file from the host machine to the contaier
sudo docker cp msmtprc zm:/etc/

Then configure Options>Email in the ZM panel ( refer the method used in the above link)
Prepare & run the zoneminder filter for emailing



Alternative method

Try the following zoneminder docker image where the MSMTP is already installed in the image
https://hub.docker.com/r/bkjaya1952/zon ... ker-latest

Then copy the msmtprc file to the docker container as follows
Suppose the name of the zoneminder container is "zm"
On the terminal run following command
sudo docker cp /etc/msmtprc zm:/etc/
Then configure Options>Email in the ZM panel
Prepare & run the zoneminder filter for emailing
