Mail issues after server restart

We did the CA server upgrade this morning and emails were broken afterwards. Nothing worked except deploying the last release again.

Environment problems

It seems like there are some steps carried out in the deployment process that set up the environment, but if the server is restarted those critical bits of environment setup are missing. This needs to be fixed. The app should have everything it needs if it's starting up after a reboot.

The CA server has been replaced again since, without update to this issue.
