No it doesn't. Seems to need some more investigation,
It logs about 10 to 100 Errors over one day with 10000 lmtp deliveries.

Perhaps you could just add some debugging into the logging for
upcoming releases, so we can identify the source of the problem?

The message "mlpath 429 < 622" actually doesn't tell me anything,
neither which user is affected, nor which session.
