Similarly, I'm using this (again, please excuse any unfortunate wrapping):
# lookup routing address in LDAP (with forwarding)
#
# 'lookup' should pass one of the following to 'extract'
# with the corresponding results
#
# "" = [fail this director]
#
# "mailRoutingAddress=bob@???"
# = bob@???
#
# "ourForwardingAddress=sally@???
# mailRoutingAddress=sally@???"
# = sally@???
ldap_with_forwarding:
driver = smartuser
new_address = ${extract \
{2}{"= "} \
{${lookup
ldap{ldap:///o=brighton.ac.uk?ourForwardingAddress,mailRoutingAddress?sub?(m
ail=$local_part@???)}}} \
{$value}fail \
}
user=exim
As Dave's only up the road from us, I've already mentioned this to him.
However, I thought I'd post it to the group as I'd really welcome comments -
particularly on performance issues - as since implementing this AND swapping
from Netscape to OpenLDAP libraries (AND upgrading to 3.32!), the mailhubs
seem a little slower...
