Default timeout for healthcheck by kubernetes is too low. As we wait up
for 2 seconds for the Postfix and DKIM to respond, this exceeds the
threshold and the healthcheck fails with:
```
Readiness probe failed: command "sh -c /scripts/healthcheck.sh" timed out
```
By simply increasing `timeoutSeconds` this issue is resolved.
From lograte man pages:
> `copytruncate`: Truncate the original log file to zero size in place after creating a copy, instead of moving the old log file and optionally creating a new one.
Why? Because file might be followed by file descriptior (and not name).
So when logrorate rotates the file, Prometheus will follow the old file
(thus receiving no metrics).
By using `comytruncate` we ensure that the followed file is always the
proper one.
We now include logrotate in the the basic image. This does -- up to a
point -- reduce the "separation of concerns", but it simplifies image
management considerably and removes an unneccessary dependency on a
third-party container.
To not repeat outselves, building of postfix-exporter was moved to a
separate action.
Helm now always references the lastest version, as there's no sense in
having specific versions which are all the same.
Lastly, the build fails in the test phase, as it relies on an external
dependency and hence tests have been (temporarily, at least) removed
from the build cycle. This should prove to be a large issue, as we're
building from a fixed SHA hash which we know to be valid.
`STARTTLS` command is not implemented because TLS is enabled on the outgoing instead of the incoming traffic.
This change enables `STARTTLS` on both ends of the connection.
