Error with multiple destination messages

[Antonio Alberto Lobato]

	(Rewrite of another previous topic...)

	Im using Postfix and Cyrus 21 (debian woody). When a user sends a
single mail to more than one recipient (with 'To: asd,teste' in compose
window), despite these msgs arrives to their destination, the sender
receives a mail msg error from postfix (with one "Mailbox does not
exist" for each recipient tried).

	When I send it to non local destinations 
(like tomlobato1 at yahoo.com,tomlobato1hotmail.com) all works fine. So, I
think my problem lies on some part of the postfix/cyrus interface.

	Can someone light what is happening ?

	Here is a edited syslog extract concerning to postfix receiveing a mail
(via smtp) and trying to delivery it to cyrus21 via lmtp. Despite errors
and a mail bounced to sender with two messages "Mailbox does not exist",
both recipients(teste at unicx.com.br and asd at unicx.com.br) received it
from sender 'tom'.
