Subject: Postfix converting ${EXTENSION} to lower case!

I'm sending deliveries to Cyrus' deliver command, but delivering to
mailboxes with caps don't work. I can't find anything about
case-sensitivity in main.cf, or at
http://postfix.affinity.net/rewrite.html ...

The alias:
shared: "|/usr/bin/awk 'NR>1 { print }' | /usr/local/cyrus/bin/deliver -m shared.${EXTENSION}"

The test:
echo test | mail shared+jobs.testimap.tellme.com
echo test | mail shared+jobs.Testimap.tellme.com

The result:
Feb 4 14:23:50 cronic postfix/local[13827]: 4217811D86: to=<shared+jobs.testcronic.tellme.com>, relay=local, delay=0, status=sent ("|/usr/bin/awk 'NR>1 { print }' | /usr/local/cyrus/bin/deliver -m shared.${EXTENSION}")
Feb 4 14:25:06 cronic postfix/local[13827]: 0833611D86: to=<shared+jobs.Testcronic.tellme.com>, relay=local, delay=0, status=bounced (user unknown. Command output: shared.jobs.test: Mailbox does not exist _ )

In the first case, the message shows up on the Cyrus server under
shared.jobs.test. In the second case, the message does not make it to

Is there something in Postfix which would be converting the delivery
address to lowercase?

Ohhh, that works like a charm. So, yes, Postfix is playing with me.
Anyone else run in to this, knows a config / patch / worksround I should
be after?
