so best will be to configure a seperate transport for ldap virtual users
that uses the macro, and let the other routers use the default
maildir_home transport for non-virtual users.

at least it works to set this macro after the router with ldap lookup.
i need this to set the path to the Maildir dynamicly. is there a better
way to do so?

yes, i use the splitted configuration scheme from debian, but this is
indeed exim4 syntax.

i have the following configuration:
--snip--
# macros:
ldap_default_servers = 127.0.0.1::389
BASEDN = ou=mail,ou=accounts,dc=resivo,dc=mejo,dc=net
GET_ADDRESS_DATA = ${lookup ldap \
    {ldap:///BASEDN??sub?(&(uid=${quote_ldap:$local_part}@${quote_ldap:$domain}))}}
GET_CATCHALL_DATA = ${lookup ldap \
    {ldap:///BASEDN??sub?(&(uid=catchall@${quote_ldap:$domain}))}}


# routers:
lookup:
driver = redirect
address_data = GET_ADDRESS_DATA
data =

localdelivery:
driver = accept
condition = ${if match {${extract{uid}{$address_data}}}{$local_part@$domain} {1}{0}}
user = mail
group = mail
transport = maildir_home
--snip--

${extract{mailMessageStore}{$address_data}} is the value of
mailMessageStore out of the ldap lookup result in $address_data.

what's wrong with that?

or do you mean the usage of .ifdef? is it for exim4 macros only? how can
i verify that ${extract{mailMessageStore}{$address_data}} has a value
before setting MAILDIR_HOME_MAILDIR_LOCATION?
