I CANT STOP RELAY !!

[James R. Stevens]

Two ways pop to mind.
 
It seems you will need the entry in your access file to allow relay of
your organization. the trick is to allow incoming/outgoing mail for
valid users only. This will stop Dictionary attacks due to the fact
sdfafafw at domain.com is not a valid account.
 
1) Do some research on /etc/host_allow .... Look at this link
http://www.sendmail.org/tips/relaying.html
 
2) Depending on your environment you can use LDAP lookup of a white list
to determine valid user accounts! I like this method.

        I have seen the same thing with MailScanner.  When I run
sendmail by itself the access db works but when I install MailScanner it
doesn't.  I have been looking into MailScanner to see if there is a way
to do this other than the access db via MailScanner.

        Would a sendmail mailing list not be more helpful? This is
clearly an 
        MTA issue and has nothing to do with MailScanner. Besides:
Posting HTML 
        mails to mailing lists is not really considered good style. 

        Sorry I have no answer for you but I am no sendmail guru...
