+Sendmail does a hostname lookup when it gets a HELO. Your resolver
+configuration may be causing that to fail and time out. Check
+<code>/etc/resolv.conf</code> and <code>/etc/hosts</code> file. Make
+sure your hostname and FQDN are both in <code>/etc/hosts</code>, and
+that hosts is looked at before DNS is queried. You probably also want
+your remote mail server to be in the hosts file.<p>
