Using phpmail() for emailings

[Liammer]

Hi there!
I'm wondering how to configure Dolibarr with Docker to send emailings with phpmail() instead of SMTP.
With ma emails' provider I have a limit of 100/hour/account... but when I send emailings, there's about 500. That's why I used sendmail (before installing Dolibarr with Docker).
Since I'm with Docker I don't know how to configure sendmail.
Here is my Dockerfile:

`FROM dolibarr/dolibarr:22.0.4
RUN apt-get update && apt-get install -y postfix libsasl2-modules &&
apt-get clean

RUN sed -i 's/myhostname = localhost.home/myhostname = myserver.com/g' /etc/postfix/main.cf
RUN echo "myorigin = myserver.com" >> /etc/postfix/main.cf
RUN sed -i 's/inet_interfaces = all/inet_interfaces = loopback-only/g' /etc/postfix/main.cf
RUN sed -i 's/inet_protocols = all/inet_protocols = ipv4/g' /etc/postfix/main.cf

RUN echo "sendmail_from = postmaster@myserver.com" >> /usr/local/etc/php/php.ini

RUN echo '#!/bin/bash\nservice postfix start\nexec "$@"' > /entrypoint-postfix.sh &&
chmod +x /entrypoint-postfix.sh
ENTRYPOINT ["/entrypoint-postfix.sh"]
CMD ["apache2-foreground"]`

I think that it is Dolibarr itself, not the docker image that should decide to use phpmail().

I don't think that the docker image has any sendmail inside it, when I run this command on the v23 image I don't find anything

find / -type f -iname sendmail

So you either need to configure your own SMTP server and run it as a different container image, or you need to make Dolibarr use phpmail() - and that happens over here: https://github.com/Dolibarr/dolibarr
