Like Jim mentioned, if it has only happened in the last few days, its fallout from worm traffic. If it has also happened in the past, depending on when it happened (does it come in spurts? happens for a few days then goes away, kind of a thing), it could have been fallout other times as well. >Here's a header (slightly expanded for easier parsing) of a mail that >just took 25 hours to reach me.

What I think I see is >Verizon getting the mail from Dow Jones only on Wed., today, tho it was >created and sent yesterday. Assuming 24 hr clocks on these servers, it looks like you are reading the headers correctly. The mail hit the Dow Jones server yesterday around noon. Then it was delayed for just under 24 hours, before being passed on to Verizon. So this could be something on the Dow Jones server that is holding the mail. My first guess would be a virus scanner that is watching all outgoing mail. Most "pro" scanners are leased based on messages per hour. So if there is a high volume of email trying to get thru, there may be a multi hour backlog of mail. However, the headers won't show you anything other than successful attempts to deliver the mail. So its also possible that something was going wrong with the connection to verizon's server, and that for 24 hours, the message failed to make it into the verizon server. This is certainly a real possibility. Depending on how the Dow Jone server is setup, it may not attempt and email more than once in a 24 hour period. If Verizon had high volume at the time the message was attempted the first time (or had a problem, or a brief outage, or Dow Jones had a connection problem, or any number of other temp failure issue), then the message may have been requeued to attempt again 24 hours later. What you would have to look for is other patterns. When these types of delays occur, is it around the same time that there are large worm outbreaks? Are the delays always from the same servers? How about the same IP subnet (could be a problem with an ISP). -chris <http://www.mythtech.net> ___________________________________________________________________________ To unsubscribe send a mail message with a SUBJECT line of "unsubscribe" to <[EMAIL PROTECTED]> or <[EMAIL PROTECTED]>
