yes it does this.

bite whom? the sending site or the receiving site?

this is a non-issue. the largest source of bounces for any well know list
is aol. e.g.
From: [log in to unmask]
Subject: Returned Mail: Undeliverable
To: [log in to unmask]
The mail you sent could not be delivered to:
550 [log in to unmask] is not a known user
550 [log in to unmask] is not a known user
550 [log in to unmask] is not a known user
550 [log in to unmask] is not a known user
552 [log in to unmask] has a full mailbox
550 [log in to unmask] is not a known user
550 [log in to unmask] is not a known user
550 [log in to unmask] is not a known user
550 [log in to unmask] is not a known user
The text you sent follows:
qmail does two things listserv admins like -- 1) it has wildcard address so
probing works and 2) it's trivial* to fix gross things like the aol bounce
above.
the same script that rewrites the aol bounce to dsn also converts qmail's
qsbmf format.
*well some formats like aol's are easy to do. some are a lot harder so we
don't bother.
