[TargetAttribute("PostmarkTarget")]
public class PostmarkTarget : AsyncTaskTarget,
IMailTargetFor best security, use an ISecretProvider (such as the KeyVaultSecretProvider to hold the API key rather than putting it in configuration files.
You can also put the connection string in your nLog.config file. Here is the typical nLog.config for this target:
<target xsi:type="PostmarkTarget"
name = "postmark"
apiKey = "super secret Postmark API key"
applicationName = "Logging.Test"
from = "application@contoso.org"
subject = "NLog sent an email"
to = "nerdly@contoso.com"

| Layout | (Inherited from TargetWithContext) |
| LayoutWithLock |
NLog Layout are by default threadsafe, so multiple threads can be rendering logevents at the same time.
This ensure high concurrency with no lock-congestion for the application-threads, especially when using AsyncTargetWrapper
or AsyncTaskTarget.
But if using custom Layout or LayoutRenderer that are not
threadsafe, then this option can enabled to protect against thread-concurrency-issues. Allowing one
to update to NLog 5.0 without having to fix custom/external layout-dependencies.
