    I've read that FAQ entry but unfortunately it doesn't really address 
this problem. The Mailman version installed is nearly the most (stable) 
recent one, so the older-version-installed problems don't apply.

    Mailman subscribe log (machine/email addresses changes to protect 
the customer :):

    Mailman smtp log:
    --------

    SMTP server log (from xinetd) shows 4 independent SMTP spawned 
processes:
    --------

    Jun 22 01:33:29 server xinetd[18538]: START: smtp pid=3370 
from=127.0.0.1
    Jun 22 01:33:29 server xinetd[18538]: START: smtp pid=3373 
from=127.0.0.1
    Jun 22 01:33:29 server xinetd[18538]: START: smtp pid=3377 
from=127.0.0.1
    Jun 22 01:33:29 server xinetd[18538]: START: smtp pid=3381 
from=127.0.0.1


    Message headers:
    --------------------

    All headers match among messages except sender/receiver MTA PID 
(obviously), the subject (there are 4 separate confirmation requests 
with individual hashes), and the message ID. *However*, the message ID 
only changes the first digit among all 4 messsages, i.e.:

    <mailman.0.1119400409.3305.mailingmoderna at modernaeditorial.com>
    <mailman.1.1119400409.3305.mailingmoderna at modernaeditorial.com>
    <mailman.2.1119400409.3305.mailingmoderna at modernaeditorial.com>
    <mailman.3.1119400409.3305.mailingmoderna at modernaeditorial.com>

    The destination address, before you ask, is not a list administrator 
(I double-checked that). I didn't copy all the message headers for the 
sake of readability, since they're all the same.

    I only mentioned that so that anyone who read this wouldn't think 
that an MTA wasn't even properly configured :)
