That may have something to do with the fact that ezmlm crafts a separate
message, with a unique SMTP sender, for each message to each list
member.  That's more expensive (in temporary storage, bandwidth, and
CPU) than Mailman's approach, but probably makes bounce-handling much
simpler for ezmlm than it is for Mailman.

On reflection, I can't understand why a auto-responder would send
auto-responses to the *list*.  They should either go to the list admin
address (if the autoresponder looks at the SMTP sender) or to the
original sender (if it looks at the "From" header).  Eg. here are some
headers from my last post to this list:
it do so!):

An autoresponder that receives this message should either look at the
return-path (a header for the SMTP sender), or the "From" header, or the
"Sender" header.  In none of those cases would it auto-respond to
mailman-users at python.org.

Hmmm: you don't happen to have "Reply-to the list" set on your list, do
