Since your ldap query is returning only 'someuser', Postfix is rewriting 
some.user at domain.com to 'someuser' (since it's an alias), and then 
adding its hostname as the @domain part. See here for more detail on that:


Your ldap query needs to return the address that you want to pass to 
deliver. So, I'm not sure from your email what address you want deliver 
to be given, but I'll guess that it should return 'someuser at domain.com' 
instead of just 'someuser'. If you are trying to pass deliver just 
'someuser' you may need to jump through some hoops in your postfix 
configuration... you're probably better off configuring dovecot to deal 
with a full email address.
