<P><FONT SIZE=2>That's exactly what I did (use brackets, send by IP address) but there is still a dependence on DNS. For example, even though I am routing by IP and configured to ignore MX, I still queue all mail if I take a DNS server out of resolv.conf. </FONT></P>

<P><FONT SIZE=2>I'm not sure if this is what you were talking about, but with the sendmail mailertable, you can list the destination via IP address. If you want the mailertable to send to the specified server regardless of it's MX record, you can put the destination address in [] brackets to avoid MX lookups.</FONT></P>
<P><FONT SIZE=2>Of course, I may have totally misunderstood your problem, in which case the above will not apply.</FONT>
