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 <A
href="mailto:sdfafafw@domain.com">sdfafafw@domain.com</A> is not a valid
account.</FONT></SPAN></DIV>

<DIV><SPAN class=054060717-25052004><FONT face=Arial color=#0000ff size=2>1) Do
some research on /etc/host_allow .... Look at this link <A

Depending on your environment you can use LDAP lookup of a white list to
determine valid user accounts! I like this method.</FONT></SPAN></DIV>

<P><FONT size=2>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. </FONT></P>

<P><FONT size=2>Would a sendmail mailing list not be more helpful? This is
clearly an</FONT> <BR><FONT size=2>MTA issue and has nothing to do with
MailScanner. Besides: Posting HTML</FONT> <BR><FONT size=2>mails to mailing
