Add: define(`confTO_QUEUEWARN', `6d')dnl ...to your sendmail.mc and rebuild sendmail.cf; this will change the DSN warning period to be longer than the (standard) bounce time, so no warning DSNs will be generated until the final bounce. This is not considered to be good practice, as most people would like a warning that the email they tried to send has not been delivered to the intended recipient sooner than that.

I don't believe you can configure different timeouts for different destinations short of setting up multiple sendmail installations with different configs. > I would still like delay DSNs sent from other mail Internet servers > to get though to my > local users too. Not a problem, aside from the fact that any DSNs someone else sends are going to be delayed just like all other mail if your Exchange server is down... Regards, -- -Chuck
