The quota_notify.py has fatal error when executed by the system, when executed manually it works.

It seems it’s unable to get the REDISPASS from the OS environment.

Steps:

  1. Create a test mailbox with 10 MB quota
  2. Sent mail with 8 MB so quota notification is triggered, wait for 1-2 minutes after email is received
  3. See quota_notify.py fatal error in docker logs (docker compose logs -f dovecot-mailcow | grep quota)

For manual execution connect to dovecot-mailcow and execute it manually.

  1. docker compose exec -it dovecot-mailcow /bin/bash
  2. /usr/local/bin/quota_notify.py 90 testmail@example.com

In the dovecot container:
printenv returns the REDISPASS
Pythons version is 3.12.8

Can someone reproduce this?

Thanks

@FreddleSpl0it looks like your commit introduced the REDISPASS variable?

Dug around a little bit, if I run the script manually from within the dovecot container it works:

docker compose exec dovecot-mailcow /bin/sh -c "python3 /usr/local/bin/quota_notify.py 80 test@domain.tld"

But in fact it’s dovecot which is running the script, and I guess dovecot isn’t aware of the REDISPASS environment variable

Probably because dovecot does not run the quota_notify script as root. I think the environment variable REDISPASS is only available for the root user

i think the best solution is to generate a config json, so the script can load it.

Also for the quarantine_notify.py I guess

mhm quarantine_notify.py is executed by ofelia as vmail user. The vmail user has REDISPASS in environment. But dovecot should also run the quota_notify.py script as vmail

No one is typing
