The OpenLDAP FAQ has many links.  My LDAP documentation is at

attributetype ( 2.16.840.1.113730.3.1.13
        NAME 'mailLocalAddress'
        DESC 'RFC822 email address of this recipient'

There is no SUBSTR matching criteria in the schema for this attribute.  
This is a pretty much part of the standard schema, you shouldn't change 
it.  I suspect if you need a SUBSTR index for this attribute you are using 
it for something other than the intended purpose (for use by an MDA in 
determining point of final delivery).  Take a look at mail -

attributetype ( 0.9.2342.19200300.100.1.3
        NAME ( 'mail' 'rfc822Mailbox' )
        DESC 'RFC1274: RFC822 Mailbox'
    EQUALITY caseIgnoreIA5Match
    SUBSTR caseIgnoreIA5SubstringsMatch
    SYNTAX 1.3.6.1.4.1.1466.115.121.1.26{256} )

if your looking to construct an addressbook, etc..  Humans should never 
care about the value of mailLocalAddress.

Alot depends upon you backend.

There is some information on tuning in my LDAP presentation.
