Legal disclaimers on emails to this group

(I've changed the original subject, "autovacuum locking question", of the
sender's email so as not to hijack that thread.)

Sorry to be off topic, but this bugs me. Language is important. This isn't
directed at you specifically, but I see these disclaimers all the time. How
can you post to a public newsgroup that automatically reproduces your email
to thousands of subscribers, and additionally publishes it on
publicly accessible archives, in direct conflict with your company's policy
appended to your email? And why on Earth do your company's lawyers think
this sort of disclaimer is helpful and even legally useful? Not to mention,
do they realize it's vaguely offensive to every customer and colleague who
receives it?
