If your message to the list came from the same host which sends the mailing
list mail to the list, it is quite likely that companyA.com's mail server is
refusing the messages.  You list message entered the Mailman-users mailing
list system here:

Received: from dns0.ssi.uk.net (unknown [62.89.146.20])
    by bag.python.org (Postfix) with ESMTP
    for <mailman-users at python.org>; Fri, 26 Aug 2005 13:05:30 +0200 (CEST)

host 62.89.146.20
20.146.89.62.in-addr.arpa domain name pointer
62-89-146-20.pool.free.th.hotchilli.net.

(Line broken by email client.)

That IP is on the Spamhaus list, and likely many others.

Check the log entries your MTA creates when you try to send a list message.
