The mailing list for listmasters using Sympa

[David Mayo <address@concealed>]

Hi guys,

I have been looking at messages that have been going missing from some 
of our mailing lists. Can anyone explain why these two messages were 
moved to the 'bad' directory:

The first is a bounce message from one of our servers:

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its

The second is a fairly standard phishing attempt. In this particular 
case obviously I don't care that it didn't get through but I would 
certainly like to know why it didn't make it through:

I have looked through the Sympa documentation and had a quick look at 
the code but it's not obvious as to why these messages were never 
delivered to the lists.

Dave.
