Second Exchange Server outgoing e-mail through wrong server

Hello,
I had Exchange 2003 mixed with one Enterprise 2003 SP2 and one 5.5 server. Our inbound frontend mail server is a TrendMicro IMMS in DMZ with public ip address that relay messages to both internal servers.
Tree SMTP connectors in our organization, IMS for the 5.5 server, one for outbound mail from exchange 2003 (until i create it every outgoing mail was trough 5.5, now sends outgoing mail with its own queues), and one for receive e-mail for other smtp domains for Exchange 2003.
We installed a second Enterprise 2003 SP2 in our organization in order to balance mailboxes and increase mail system availability. I can receive mail from outside, send internal mails, but for outgoing internet mail, this second server try to use ¡our frontend internet mail! . As i have relay restriction at this server, i get messages like "550 relying denied...".

I did some test for using smart host against our public server, but i'm almost sure i delete all references to that. I can allow relay for my internal server on the IMMS server, but i want to choose the smarthost option, not to be forced.

Please, where is the problem?
Additional info, i have Scanmail for Exchange in the two Exchange 2003 servers

Thanks in Advance

Do you have smart hosts configured on the SMTP virtual servers? If you do remove them.
SMTP connectors are used to control the message flow. The server listed as the bridgehead is the server that tries to relay email out to the internet. If you don't have any SMTP connectors then you need to create at least one.

No smart hosts defined in the second server. I have tried to stop the default smpt virtual server and create another one with defaults but unsuccessful.
I have tried with the two Exchange 2003 servers as local bridgheads...
I have run smtpdiag and all OK...
