This would be a very bad default. I can vouch for the impact of a few thousand hosts that are all ntp sync'ed hitting a server at once... sendmail -q30m has the advantage of having a fairly random distribution of retry events over the hour with a significant number of hosts. eg: host 1 might be using 14,44 past the hour, host 2 might be on 3,33 etc. Cheers, -Peter -- Peter Wemm - peter@FreeBSD.org; peter@yahoo-inc.com; peter@netplex.com.au "All of this is for nothing if we don't go to the stars" - JMS/B5 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
