check the online exim4 documentation for the required ldap lookups.

basically not, but it depends on your environment.
i use the objectclass and attributes defined by the lachman-laser draft.
openldap includes them in the misc.schema and they are sufficient for
hosting virtual domains.

well, this is basically how i do it:

all user entries contain the inetLocalMailRecipient objectclass and i
use these attributes:

mail: <mailbox>@<domain>
the "real" mailbox

mailHost: <hostname>
the hostname of the imap store where the mailbox is located

mailLocalAddress: <local_part>@<domain>
virtual e-mail aliases for the defined mailbox.

exim searches the LDAP directory using the mailLocalAddress attribute.
it rewrites the envelope recipient with the value returned in the mail
attribute and delivers the mail to the host defined in the mailHost
attribute.

hth,
tom.
