Re: how to debug sendmail relaying denied problems?

[eyang@xxxxxxxxx (Eric Yang)]

This means the sendmail does not know how to handle dbmscan.com.  It's doing

DNS record lookup.  You need to add your hostname to the local host setting.

If it's a mail relay, then you need to add dbmscan.com to the Relay Settings.

Hope this helps.

regards,

Eric
