hi at all
I´ve a problem when send messages to a provider that requires us to stablish a tls connection an then send it a user name and password.
On my old MTA these scenario works fine, but if i use our news C360 appliances I cannot deliver messages to the provider. On the logs of the appliances i can see the TLS session stablished but appears that the c360 don not send the credentials...
The log seems like this:
SMTP delivery connection (DCID 153865) opened from IronPort interface 194.xxx.yyy.zzz to IP address 194.aaa.bbb.ccc on port 25.
23 Oct 2009 12:01:45 (GMT +0200)
Delivery connection (DCID 153865) successfully accepted TLS protocol TLSv1 cipher RC4-MD5 .23 Oct 2009 12:01:45 (GMT +0200)

(DCID 153865) Delivery started for message 186001 to [email protected].23 Oct 2009 12:01:46 (GMT +0200)
(DCID 153865) Message 186001 to [email protected] bounced by destination server. Reason: 5.1.0 - Unknown address error ('505', ['5.7.3 Client was not authenticated'])
Any help will be appreciated
