"Pretending" to be another mail domain on RHEL 2.1

[Jose Goyana_3]

Hi!
My hostname is abc.bank.sa and changing it wouldn't be viable because OracleAS is installed there.
I wish to send emails to the Internet through an automated Linux routine using a SMTP relay BUT, as long as current SMTP servers do reverse DNS, I do need to send emails as if machine's domain was bank.com.br
What could I possibly do?

Regards,
Jose

Shalom Jose,

Quick and dirty: Set the Dj directive in /etc/sendmail.cf

Make sure the public DNS records match the Dj statement.

Djbank.com.br

service sendmail restart
