You are reffering to :

       /usr/sbin/sendmail -bd -ODeliveryMode=defer \

And i use :

# SMTP host and port, when DELIVERY_MODULE is 'SMTPDirect'
SMTPPORT = 25 is sendmail.
This is doing the DNS lookups?
Can i just do SMTPHOST = '' witch is another SMTP server at my
LAN (windows 2000 server with Mailtraq )?
Is it then not using sendmail and DNS troubles at all?

What are the actions to prevent it?
So this file must be in normal operation empty?
