It flushes to the highest priority MX, so you need to point the highest priority MX at their mail server (unless that's down, in which case it goes to the next highest, and so on). ETRN essentially runs 'sendmail -q<domain.name>' to flush mail, thus it'll only go to the wrong server if their higher priority MX addresses are misconfigured. -- Brian Cully <shmit@erols.com> ``And when one of our comrades was taken prisoner, blindfolded, hung upside-down, shot, and burned, we thought to ourselves, `These are the best experiences of our lives''' -Pathology (Joe Frank, Somewhere Out There) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
