sendmail slower after 9 to 10 upgrade

[chuckdevguy]

Since upgrading from 9-rel to 10-rel sendmail is pausing for 5-8 seconds below:


mail -v -s "test from web1" test@test.com

.
EOT

test@test.com... Connecting to [127.0.0.1] via relay...


***the above line takes 5 seconds then the rest of the output is quick and sends the e-mail fine
