Ambiguous logs in sender.js

[Gladiak]

Hello guys,
we need to parse the logs that zone-mta composes in the sender.js file to notify the outcome of email delivery.

By checking the code you can see that they have the form:
'id=%s %s.%s ACCEPTED from=%s to=%s src=%s mx=%s id=%s (%s)'

The id entry is repeated to refer to both the session id and the message id.

Would it be possible to remove this ambiguity ?
For example by substituting “message-id” or similar for id when referring to the message.
If you prefer, i could make a PR to fix this.

Have a great day
