Mixed case incoming e-mail addresses being bounced.

From: Edward Rudd (no email)

I have my mail server setup using postfix 2.0.16 and cyrus imapd 2.2.3
using the virtdomains: userid in cyrus and the virtual_transport in
postfix using virtual_mailbox_maps and virtual_mailbox_domains for
allowed mail account lookups. One of the accounts on the system has been
having e-mail delivered to it bounce, with an "no mailbox found" error
for cyrus' lmtp, but only with some e-mails.. and from the logs it seems
it is the e-mails that have mixed case.. ie. , get
bounced but not the *normal* case..

Is there anyway I can have either postfix or cyrus lower the case on the
e-mail address? (but not the + recipient_delimiter information)

Here are my logs..
