Hi,

I installed sendmail in RHEL5.4 with TrendMicro Spam scan engine.
The configuration like sendmail should forward all the mails to scan engine after scanning it will deliver it to the mail domains. same way all the mails coming from external servers are scanned and the delivered to local box.

My problem is when i sent mail for local users its delivered locally. but when i sending mail for external like yahoo.. its going through scan engine.

I added the smarthost in sendmail.mc file also.

Need help to know what's wrong i done in configuration.

Local mail is handled by the submit.mc configuration file. My guess is
that you can set up the smarthost for local delivery in the same way
you configure the sendmail.mc.
