I'm not sure yet if this is Qmail specific, but I thought that someone
here might have experienced this before and thus would have an idea since
we're all email Admins.
Users who are sending our mail servers mail from large sites such as
prontomail or hotmail occasionally get the following error:
>From: [EMAIL PROTECTED]
>To: [EMAIL PROTECTED]
>Subject: Delivery Status Notification (Failure)
>Date: Thu, 7 Sep 2000 13:31:04 -0700

The odd thing about this is that we have two mail servers - one in New
Jersey on an occasionally unstable link and one in California at Above.net
which is always online and both trigger this error (randomly).
Both of these mail servers run Qmail 1.03 and Ezmlm which is really the
only similarity between them. We have clients who send and retrieve mail
from both mail servers all day long so I "know" that these are not offline
- and while it's possible for short periods of inaccessibility, shouldn't
these messages queue for at least a few hours before bouncing?
Or is this error message indicative of something else?
