Each unique message has a unique ID, duplicates will not. Duplicates *should* be killable with inpunity. However, it's not completely impossible for a random ID to non-unique, even if highly improbable. Though, if you have other headers that are the same, then it's very very likely that it's a duplicate message. There are mail clients with built-in, or add-on, functions to kill duplicates. They'll do the job not caring if the duplicate is because the original poster sent twice, a mail server resent a message it thought didn't pass through, or a mail client downloaded the same message more than once. -- [tim@bigblack ~]$ uname -ipr 2.6.23.12-52.fc7 i686 i386 Don't send private replies to my address, the mailbox is ignored.
