NDRs on emails that get delivered
Posted on 2003-11-03
Some users are occasionally getting ndr's on internet emails, but the emails reach their destination (75 - 95% of the time). It seems like these emails are occasionally delayed too (take up to a couple hrs to be received).
Follows is an ndr for a email a user sent to my netzero account. i received the email and the user received this:
Your message did not reach some or all of the intended recipients.
Subject: test 1102
Sent: 11/3/03 11:03 AM
The following recipient(s) could not be reached:

There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
< mx03.gis.net #2.5.0 smtp; 250 OK id AAA94N9A5ASY7DCJ (from netzero.com:22.214.171.124)>
We have had our isp (gis) for some time and nothing has been recently changed in our configuration. The problem does not occur all the time (ie- perhaps every 3rd or 4th email sent to a specific address), but often enough to be really frustrating.
At one point I believed the problem to have been related to delivery and read receipts, but this does not seem to be the case, as the problem occurs even with receipts off.
Any help is greatly appreciated
