IIS 7, using IIS 6 for SMTP mail, but it reverts emails to be lowercase

Hi,
Is there a quick route to change IIS7 or IIS6 actually to stop flattening all the email addresses to lowercase letters when sending through the SMTP subsystem?

Thanks,
Kerj!

please elaborate

1. David <David@example.com> changed to David <david@example.com> ?
2. David <David@example.com> changed to david <david@example.com> ?

The domain name will ALWAYS be lower-case and it is suggested that when creating a new email address to ALWAYS use lower-case as even though it is in the standard that David@... and david@... are different email addresses  (most providers only use lowercase names)

RFC 2821
This    is NOT true of a mailbox local-part.  The local-part of a mailbox    MUST BE treated as case sensitive.  Therefore, SMTP implementations    MUST take care to preserve the case of mailbox local-parts.  Mailbox    domains are not case sensitive.  In particular, for some hosts the    user "smith" is different from the user "Smith".  However, exploiting    the case sensitivity of mailbox local-parts impedes interoperability    and is discouraged.

Hi ve3ofa,
Thanks for your examples.  No1 is the situation I am.
1. David <David@example.com> changed to David <david@example.com> ?

If only another admin would listen and agree.. I have always used lowercase, but I have a situation where the admin doesn't want this and it is now for me to fix.

Thanks again.
