Hi all,
after upgrading from SLES8 to SLES9 -> postfix-2.1.1-1.17, 
postfix is configured as smpt-auth client against a windows2003 server.
I have noticed that postfix sends the following string

> MAIL FROM:<user <at> domain> AUTH=<>

(this didn't happen with SLES8 - postfix-1.1.12-12 - i mean the empty AUTH)
and this mail is rejected from the windows2003 server with the following message
> 454 5.7.3 Client does not have permission to Send As this sender

the authentication itself works
250 OK
AUTH LOGIN
334 VXNlcm5hbWU6
cmRwdXNlcjM=
334 UGFzc3dvcmQ6
cmRwdXNlcjM=
235 2.7.0 Authentication successful.
MAIL FROM:<user <at> domain> AUTH=<>
-----
without this AUTH=<> or with AUTH=<user> windows2003 accepts the mail.

how can i 
1. tell postfix not to send the empty AUTH=<>
2. or tell postfix to add the username to AUTH=<user>

TIA

Khai
