Check this values in your sendmail.cf notice that "queuewarn" is higher than
"queuereturn", so my sendmail nevers send the DSN saying "we cant send your
email but we are still trying" we only send the DSN "sorry after 5 days we
could not send your email"

O Timeout.queuereturn=5d
#O Timeout.queuereturn.normal=5d
#O Timeout.queuereturn.urgent=2d
#O Timeout.queuereturn.non-urgent=7d
#O Timeout.queuereturn.dsn=5d
O Timeout.queuewarn=8d
