Comment (by Jeff McKenna):

 I've examined the logs closely and spent my whole day on this.  (funding,
 anyone?)

 The original issue reported in this ticket (spam from qq.com domain) still
 exists.

 * Typical log message today showing successful emails sent to our list
 owners:

 {{{
 Jun 18 11:08:51 osgeo6 postfix/qmgr[23549]: 173A7600C6B7:
 from=<123725849 at qq.com>, size=956, nrcpt=1 (queue active)
 Jun 18 11:08:51 osgeo6 postfix/pipe[24762]: 173A7600C6B7: to=<mapguide-
 internals-owner at lists.osgeo.org>, relay=mailman, delay=0.69,
 delays=0.54/0/0/0.15, dsn=2.0.0, status=sent (delivered via mailman
 service)
 }}}

 * So I examined our postfix config files.
 * /etc/postfix/access contains:  qq.com REJECT
 * so something wasn't right, because the qq.com domain is not being
 rejected
 * I noticed that the config file /etc/postfix/main.cf was missing the
 important line:
 {{{
 smtpd_sender_restrictions = check_sender_access hash:/etc/postfix/access
 }}}
 * restarted service
 * logs say that qq.com now REJECTS the qq.com domain:
 {{{
 Jun 18 11:35:04 osgeo6 postfix/smtpd[17873]: NOQUEUE: reject: RCPT from
 unknown[114.228.74.19]: 554 5.7.1 <676479210 at qq.com>: Sender address
 rejected: Access denied; from=<676479210 at qq.com> to=<discuss-
 bounces at lists.osgeo.org> proto=SMTP helo=<mail.tofine.com>
 }}}
 * but that slows the queue as postfix tries to send a rejection email to a
 broken qq.com sender.  So updated the access file to DISCARD instead, when
 allows postfix to crunch faster:
 {{{
 Jun 18 11:40:23 osgeo6 postfix/smtpd[20305]: NOQUEUE: discard: RCPT from
 unknown[125.121.117.70]: <491235343 at qq.com>: Sender address triggers
 DISCARD action; from=<491235343 at qq.com> to=<gdal-dev-
 owner at lists.osgeo.org> proto=SMTP helo=<chinarida.com.cn>

 I am watching the logs being processed now.  I hope this change helps!!!
