Hello everybody,
I forgot to add a complete transaction sample of local delivery.
The following log depicts a mail delivery with two recipients; 10.1.1.1
is the last hop MTA server that calls lmtp for local delivery; the first
recipient got a correct uid while the second gets a "uid=error"; both
mails got delivered to INBOX correctly....
Thankyou in advance
Best regards
Giorgio
