python - changing apache2 envvar causes crash & does not send mail content

Question

I have a flask applcation running on apache2 server. I wrote a test script in python to send mails using postfix:

import os
def send_mail(to, subject, msg):
    os.system(f"echo {msg} | mail -s '{subject}' to")

When i run this script, it sends a mail to the target with the sender name like '[email protected]'. This is good. But, when I try to run same code in flask app, mail sender becomes '[email protected]' and I can't see any mail content. I tried to change envvars in /etc/apache2/envvars:

export APACHE_RUN_USER=www-data
export APACHE_RUN_GROUP=www-data

to:

export APACHE_RUN_USER=root
export APACHE_RUN_GROUP=root

(I have only one user and it's root) but this time, apache unable to start saying

'[core:warn] [pid 38691] AH00111: Config variable ${APACHE_RUN_DIR} is not defined
apache2: Syntax error on line 80 of /etc/apache2/apache2.conf: DefaultRuntimeDir must be a valid directory, absolute or relative to ServerRoot'

any ideas to fix this issue?
