Hi,

I've just implemented a new mail platform using Cyrus IMAPd 2.1.11 and Exim
4.12, and I wonder... how to deal with the fact that systems don't allways
do want you expect..?

It seem to me that exim/cyrus has problem with delivery of mail if the
mail-address are written in another case than the mailbox-name... E.g. user
fridao@mydomain can't receive mail if the sender uses mail-address
Fridao@mydomain. How should I deal with that?

I have a router like this in my Exim 4.1x setup talking to Cyrus (at the appropriate place in the sequence, i.e. just before your Cyrus deliver router):

lowercase_local:
driver = redirect
domains = +local_domains
redirect_router = local
data = ${lc:${local_part}}

with the Cyrus delivery router being named "local".
