[exim] LDAP lookup caching

Hi all,

I use ldap lookup for acl, transport, routing, vacations, ...

I've read in the documentation that there are no inter-process
caching facility

Can I reasonably set something like : addresslist localaddresses = $
{lookup ldap ...

for 400 mail addresses ?

Can I update this list by a killall -HUP exim4 ?


Thanks,

Cyril Feraudet
