Problem with courier-imap-3.0.8 + qmail-ldap

["sato x" <gladiol4@gmail.com>]

Hi...

I've just succeeded installing courier-imap version 3 (because
courier-imap-4 got me headaches only) and use squirrel mail to login
into my account with username sato only (the same as the uid in ldap
server). The problem is, after I send email to other domain and user
there wants to reply to that email, the replying address is
sato@domain.co.id and not the real email address in mail attribute,
that is sato.br@domain.co.id. I tried to edit
/usr/lib/courier-imap/etc/authldaprc and do the svc -t /service/imapd,
but it didn't help at all.  What is the problem here? Thank you in
advance for helping me (and all the helps you gave before). 

Best regards,

sato
