No Mail Box

[Greg Sidleinger]

Ok I don't know if this is a cyrus problem or a postfix problem but when
ever I try to send email to a mail box with a odd case ( GAte at domain.com
) the email bounces.  I created mail boxes in lower case and just
noticed that the email bounced when sending to it in a case other than
it was created with.  Could anyone tell me how to fix this because I
know I did not have this problem before upgrading to impad2 2.1.11 from
a 2.0.x version.
