I think the matching should be case-insensitive.

at least in every large installation LDAP User Backend's (or AD or
similar) are used, and they are definitly case insensitive for the CN or
UID attributes. Really nobody who cares about his systems and users uses
mailboxnames which just differ in case (too much danger of confusion!)

At least sieve must reflect the same settings as the MDA, so if the MDA
is set to downcase (which in my opionion is the only valuable setting)
sieve must also downcase.

Sincerly,
Klaus

Every Unix/Linux system (I’d say that represents the majority of mail systems) 
has a case sensitive local part. Most mail admins have set their systems up to 
normalize all users on lowercase names, but that is not and has not always been 
the case.

Message handling systems MUST preserve case, systems delivering messages
to a mailbox SHOULD ignore case.

RFCs, especially earlier ones, require local-part to be case senstive
but that was a poorly thought out directive and the world largely
ignored it.

The local part of an email domain has absolutely nothing to do with any
(local or non-local) user account - and who says that there are any user
accounts/logins (apart from root and so-called system users) on the mail
system?
Yes, it *could* have something to do, and yes it actually may often be
the case but that's just a - intended or not intended - coincidence

Isn't the user name in the original Unix mail system (and presumably 
most of its descentants) case sensitive?  In which case it has to 
distinguish between mail sent to bob and to Bob?

Just change auth_username_format = %Lu to make all addresses lowercase. That

Or if you REALLY REALLY want to have case-sensitive userpart, then use 
auth_username_format = %n@%Ld

It seems there is a misunderstanding. In Pigeonhole Sieve version 
0.5.7.2, the vacation module compares the additional :addresses 
case-sensitive.

I want to have it case-insensitive again, like in Pigeonhole version 0.4.24
