To enable protocol logging in exchange 2007 you need to do it on either the Recieve Connector or the Send Connector themselves.

To enable outbound SMTP logging use Set-SendConnector "Connector Name" -ProtocolLoggingLevel verbose. By default it is set to none.

To enable inbound SMTP logging use Set-RecieveConnector "Connector Name" -ProtcolLoggingLevel verbose. By default it is set to none.

By default outbound logs are stored here:
C:\Program Files\Microsoft\Exchange Server\TransportRoles\Logs\ProtocolLog\SmtpSend

By default inbound logs are stored here:
C:\Program Files\Microsoft\Exchange Server\TransportRoles\Logs\ProtocolLog\SmtpReceive
