if a user does an update on p5-Mail-SpamAssassin from an older version (3.2.5) sa-update channel does not get updated.

older versions (/var/db/spamassassin/3.002005/updates_spamassassin_org/MIRRORED.BY) had this in it: (from june 2008)

test mirror: zone, cached via Coral
#http://buildbot.spamassassin.org.nyud.net:8090/updatestage/
http://spamassassin.kludge.org/updates/

sa-update would fail to find updates spamassassin.kludge.org no longer exists)

if sa-update files to find host, it won't update. and won't update MIRRORED.BY

Fix: remove old mirrored.by and sa-update will replace mirrored.by and do the update.

new mirrored.by (today) has this:

# test mirror: zone, cached via Coral
#http://buildbot.spamassassin.org.nyud.net:8090/updatestage/
http://daryl.dostech.ca/sa-update/asf/ weight=5
http://www.sa-update.pccc.com/ weight=5

these patches to port will delete old MIRRORED.BY during (re) install if sa-update fails with rc==4

only issue would be an integrator with a custom MIRRORED.BY (and a failure)
How-To-Repeat: check old mirrored by.
replace mirrored.by with the above
run sa-update.
