## `dkimsign` causes parsing errors in post-data hook (0.07 to 1.5)

The default post-data hook in versions 0.07 to 1.5 has a bug where if the
`dkimsign` command exists, unwanted output will be emitted and cause the
post-data hook invocation to fail.

The problem can be identified by the following error in the logs:

```
Hook.Post-DATA 1.2.3.4:5678: error: error parsing post-data output: \"/usr/bin/dkimsign\\n...
```

As a workaround, you can edit the hook and make the change
[seen here](https://blitiri.com.ar/git/r/chasquid/c/b6248f3089d7df93035bbbc0c11edf50709d5eb0/).

The issue is fixed in 1.6.
