msmtp doesn't have permission to create a log

[insanity54]

I noticed that when osticket sends emails, the following error appears in /var/log/php5-fpm.log--

WARNING: [pool www] child 17 said into stderr: "msmtp: cannot log to /var/log/msmtp.log: cannot open: Permission denied"

When I investigated, I found that the logfile /var/log/msmtp.log which is configured in msmtp.conf doesn't exist--

docker exec -it osticket /bin/bash -c 'ls -la /var/log/msmtp.log'
ls: cannot access /var/log/msmtp.log: No such file or directory

So it seems that the PHP user www-data doesn't have write access for /var/log/.

I'm not sure if this is the best way to fix this, but here's my proposed solution. In the Dockerfile, add these lines--

touch /var/log/msmtp.log
chown root:www-data /var/log/msmtp.log
chmod 0664 /var/log/msmtp.log

Thanks for the report. The Dockerfile has been updated to allow www-data write permission to the log file.
